Struct Session 

#[non_exhaustive]
pub struct Session {
    pub name: String,
    pub labels: HashMap<String, String>,
    pub create_time: Option<Timestamp>,
    pub approximate_last_use_time: Option<Timestamp>,
    pub creator_role: String,
    pub multiplexed: bool,
    /* private fields */
}

A session in the Cloud Spanner API.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

name: String

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

labels: HashMap<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’s 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. Use a multiplexed session for multiple, concurrent operations including any combination of read-only and read-write transactions. Use sessions.create to create multiplexed sessions. Don’t use BatchCreateSessions to create a multiplexed session. You can’t delete or list multiplexed sessions.

Implementations

impl Session

pub fn new() -> Self

Creates a new default instance.

pub fn set_name<T: Into<String>>(self, v: T) -> Self

Sets the value of name.

pub fn set_labels<T, K, V>(self, v: T) -> Self

where T: IntoIterator<Item = (K, V)>, K: Into<String>, V: Into<String>,

Sets the value of labels.

pub fn set_create_time<T>(self, v: T) -> Self

where T: Into<Timestamp>,

Sets the value of create_time.

pub fn set_or_clear_create_time<T>(self, v: Option<T>) -> Self

where T: Into<Timestamp>,

Sets or clears the value of create_time.

pub fn set_approximate_last_use_time<T>(self, v: T) -> Self

where T: Into<Timestamp>,

Sets the value of approximate_last_use_time.

pub fn set_or_clear_approximate_last_use_time<T>(self, v: Option<T>) -> Self

where T: Into<Timestamp>,

Sets or clears the value of approximate_last_use_time.

pub fn set_creator_role<T: Into<String>>(self, v: T) -> Self

Sets the value of creator_role.

pub fn set_multiplexed<T: Into<bool>>(self, v: T) -> Self

Sets the value of multiplexed.

Trait Implementations

impl Clone for Session

fn clone(&self) -> Session

Returns a duplicate 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() -> Session

Returns the “default value” for a type.

impl Message for Session

fn typename() -> &'static str

The typename of this message.

impl PartialEq for Session

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

Tests for self and other values to be equal, and is used by ==.

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

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