Struct google_api_proto::google::spanner::v1::Session

pub struct Session {
    pub name: String,
    pub labels: BTreeMap<String, String>,
    pub create_time: Option<Timestamp>,
    pub approximate_last_use_time: Option<Timestamp>,
    pub creator_role: String,
    pub multiplexed: bool,
}

A session in the Cloud Spanner API.

Fields

name: String

Output only. The name of the session. This is always system-assigned.

labels: BTreeMap<String, String>

The labels for the session.

• Label keys must be between 1 and 63 characters long and must conform to the following regular expression: [a-z](\[-a-z0-9\]*[a-z0-9])?.
• Label values must be between 0 and 63 characters long and must conform to the regular expression ([a-z](\[-a-z0-9\]*[a-z0-9])?)?.
• No more than 64 labels can be associated with a given session.

See https://goo.gl/xmQnxf for more information on and examples of labels.

create_time: Option<Timestamp>

Output only. The timestamp when the session is created.

approximate_last_use_time: Option<Timestamp>

Output only. The approximate timestamp when the session is last used. It is typically earlier than the actual last use time.

creator_role: String

The database role which created this session.

multiplexed: bool

Optional. If true, specifies a multiplexed session. A multiplexed session may be used for multiple, concurrent read-only operations but can not be used for read-write transactions, partitioned reads, or partitioned queries. Multiplexed sessions can be created via [CreateSession][google.spanner.v1.Spanner.CreateSession] but not via [BatchCreateSessions][google.spanner.v1.Spanner.BatchCreateSessions]. Multiplexed sessions may not be deleted nor listed.

Trait Implementations

impl Clone for Session

fn clone(&self) -> Session

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Session

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

Formats the value using the given formatter.

impl Default for Session

fn default() -> Self

Returns the “default value” for a type.

impl Message for Session

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 Session

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