Struct google_api_proto::google::spanner::admin::database::v1::CrontabSpec

pub struct CrontabSpec {
    pub text: String,
    pub time_zone: String,
    pub creation_window: Option<Duration>,
}

CrontabSpec can be used to specify the version time and frequency at which the backup should be created.

Fields

text: String

Required. Textual representation of the crontab. User can customize the backup frequency and the backup version time using the cron expression. The version time must be in UTC timzeone.

The backup will contain an externally consistent copy of the database at the version time. Allowed frequencies are 12 hour, 1 day, 1 week and 1 month. Examples of valid cron specifications:

• 0 2/12 * * * : every 12 hours at (2, 14) hours past midnight in UTC.
• 0 2,14 * * * : every 12 hours at (2,14) hours past midnight in UTC.
• 0 2 * * * : once a day at 2 past midnight in UTC.
• 0 2 * * 0 : once a week every Sunday at 2 past midnight in UTC.
• 0 2 8 * * : once a month on 8th day at 2 past midnight in UTC.

time_zone: String

Output only. The time zone of the times in CrontabSpec.text. Currently only UTC is supported.

creation_window: Option<Duration>

Output only. Schedule backups will contain an externally consistent copy of the database at the version time specified in schedule_spec.cron_spec. However, Spanner may not initiate the creation of the scheduled backups at that version time. Spanner will initiate the creation of scheduled backups within the time window bounded by the version_time specified in schedule_spec.cron_spec and version_time + creation_window.

Trait Implementations

impl Clone for CrontabSpec

fn clone(&self) -> CrontabSpec

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CrontabSpec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CrontabSpec

fn default() -> Self

Returns the “default value” for a type.

impl Message for CrontabSpec

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(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

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

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

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

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for CrontabSpec

fn eq(&self, other: &CrontabSpec) -> 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.
