    pub min_time_elapsed_since_last_modification: Option<Duration>,

}

Conditions that determine which objects are transferred. Applies only to Cloud Data Sources such as S3, Azure, and Cloud Storage.

The “last modification time” refers to the time of the last change to the object’s content or metadata — specifically, this is the updated property of Cloud Storage objects, the LastModified field of S3 objects, and the Last-Modified header of Azure blobs.

Transfers with a [PosixFilesystem][google.storagetransfer.v1.PosixFilesystem] source or destination don’t support ObjectConditions.

Fields

min_time_elapsed_since_last_modification: Option<Duration>

Ensures that objects are not transferred until a specific minimum time has elapsed after the “last modification time”. When a [TransferOperation][google.storagetransfer.v1.TransferOperation] begins, objects with a “last modification time” are transferred only if the elapsed time between the [start_time][google.storagetransfer.v1.TransferOperation.start_time] of the TransferOperation and the “last modification time” of the object is equal to or greater than the value of min_time_elapsed_since_last_modification`. Objects that do not have a “last modification time” are also transferred.

max_time_elapsed_since_last_modification: Option<Duration>

Ensures that objects are not transferred if a specific maximum time has elapsed since the “last modification time”. When a [TransferOperation][google.storagetransfer.v1.TransferOperation] begins, objects with a “last modification time” are transferred only if the elapsed time between the [start_time][google.storagetransfer.v1.TransferOperation.start_time] of the TransferOperationand the “last modification time” of the object is less than the value of max_time_elapsed_since_last_modification`. Objects that do not have a “last modification time” are also transferred.

include_prefixes: Vec<String>

If you specify include_prefixes, Storage Transfer Service uses the items in the include_prefixes array to determine which objects to include in a transfer. Objects must start with one of the matching include_prefixes for inclusion in the transfer. If [exclude_prefixes][google.storagetransfer.v1.ObjectConditions.exclude_prefixes] is specified, objects must not start with any of the exclude_prefixes specified for inclusion in the transfer.

The following are requirements of include_prefixes:

• Each include-prefix can contain any sequence of Unicode characters, to a max length of 1024 bytes when UTF8-encoded, and must not contain Carriage Return or Line Feed characters. Wildcard matching and regular expression matching are not supported.

• Each include-prefix must omit the leading slash. For example, to include the object s3://my-aws-bucket/logs/y=2015/requests.gz, specify the include-prefix as logs/y=2015/requests.gz.

• None of the include-prefix values can be empty, if specified.

• Each include-prefix must include a distinct portion of the object namespace. No include-prefix may be a prefix of another include-prefix.

The max size of include_prefixes is 1000.

For more information, see Filtering objects from transfers.

exclude_prefixes: Vec<String>

If you specify exclude_prefixes, Storage Transfer Service uses the items in the exclude_prefixes array to determine which objects to exclude from a transfer. Objects must not start with one of the matching exclude_prefixes for inclusion in a transfer.

The following are requirements of exclude_prefixes:

• Each exclude-prefix can contain any sequence of Unicode characters, to a max length of 1024 bytes when UTF8-encoded, and must not contain Carriage Return or Line Feed characters. Wildcard matching and regular expression matching are not supported.

• Each exclude-prefix must omit the leading slash. For example, to exclude the object s3://my-aws-bucket/logs/y=2015/requests.gz, specify the exclude-prefix as logs/y=2015/requests.gz.

• None of the exclude-prefix values can be empty, if specified.

• Each exclude-prefix must exclude a distinct portion of the object namespace. No exclude-prefix may be a prefix of another exclude-prefix.

• If [include_prefixes][google.storagetransfer.v1.ObjectConditions.include_prefixes] is specified, then each exclude-prefix must start with the value of a path explicitly included by include_prefixes.

The max size of exclude_prefixes is 1000.

For more information, see Filtering objects from transfers.

last_modified_since: Option<Timestamp>

If specified, only objects with a “last modification time” on or after this timestamp and objects that don’t have a “last modification time” are transferred.

The last_modified_since and last_modified_before fields can be used together for chunked data processing. For example, consider a script that processes each day’s worth of data at a time. For that you’d set each of the fields as follows:

• last_modified_since to the start of the day

• last_modified_before to the end of the day

last_modified_before: Option<Timestamp>

If specified, only objects with a “last modification time” before this timestamp and objects that don’t have a “last modification time” are transferred.

Trait Implementations

impl Clone for ObjectConditions

fn clone(&self) -> ObjectConditions

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

fn default() -> Self

Returns the “default value” for a type.

impl Message for ObjectConditions

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

impl PartialEq for ObjectConditions

fn eq(&self, other: &ObjectConditions) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
