Struct google_api_proto::google::spanner::executor::v1::Concurrency

pub struct Concurrency {
    pub snapshot_epoch_read: bool,
    pub snapshot_epoch_root_table: String,
    pub batch_read_timestamp_micros: i64,
    pub concurrency_mode: Option<ConcurrencyMode>,
}

Concurrency for read-only transactions.

Fields

snapshot_epoch_read: bool

True if exact_timestamp_micros is set, and the chosen timestamp is that of a snapshot epoch.

snapshot_epoch_root_table: String

If set, this is a snapshot epoch read constrained to read only the specified log scope root table, and its children. Will not be set for full database epochs.

batch_read_timestamp_micros: i64

Set only when batch is true.

concurrency_mode: Option<ConcurrencyMode>

Concurrency mode set for read-only transactions, exactly one mode below should be set.

Trait Implementations

impl Clone for Concurrency

fn clone(&self) -> Concurrency

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Concurrency

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

Formats the value using the given formatter.

impl Default for Concurrency

fn default() -> Self

Returns the “default value” for a type.

impl Message for Concurrency

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 Concurrency

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