Struct QuerySessionContext 

#[non_exhaustive]
pub struct QuerySessionContext {
    pub query_id: Option<String>,
    pub query_start_time: Option<DateTime>,
    pub cluster_id: Option<String>,
    pub query_authorization_id: Option<String>,
    pub additional_context: Option<HashMap<String, String>>,
}

A structure used as a protocol between query engines and Lake Formation or Glue. Contains both a Lake Formation generated authorization identifier and information from the request's authorization context.

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.

query_id: Option<String>

A unique identifier generated by the query engine for the query.

query_start_time: Option<DateTime>

A timestamp provided by the query engine for when the query started.

cluster_id: Option<String>

An identifier string for the consumer cluster.

query_authorization_id: Option<String>

A cryptographically generated query identifier generated by Glue or Lake Formation.

additional_context: Option<HashMap<String, String>>

An opaque string-string map passed by the query engine.

Implementations

impl QuerySessionContext

pub fn query_id(&self) -> Option<&str>

A unique identifier generated by the query engine for the query.

pub fn query_start_time(&self) -> Option<&DateTime>

A timestamp provided by the query engine for when the query started.

pub fn cluster_id(&self) -> Option<&str>

An identifier string for the consumer cluster.

pub fn query_authorization_id(&self) -> Option<&str>

A cryptographically generated query identifier generated by Glue or Lake Formation.

pub fn additional_context(&self) -> Option<&HashMap<String, String>>

An opaque string-string map passed by the query engine.

impl QuerySessionContext

pub fn builder() -> QuerySessionContextBuilder

Creates a new builder-style object to manufacture QuerySessionContext.

Trait Implementations

impl Clone for QuerySessionContext

fn clone(&self) -> QuerySessionContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QuerySessionContext

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

Formats the value using the given formatter.

impl PartialEq for QuerySessionContext

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