Struct ExecutionContext

pub struct ExecutionContext {
    pub database_identity: Identity,
    pub reducer: Option<ReducerContext>,
    pub workload: WorkloadType,
}

Represents the context under which a database runtime method is executed. In particular it provides details about the currently executing txn to runtime operations. More generally it acts as a container for information that database operations may require to function correctly.

Fields

database_identity: Identity

The identity of the database on which a transaction is being executed.

reducer: Option<ReducerContext>

The reducer from which the current transaction originated.

workload: WorkloadType

The type of workload that is being executed.

Implementations

impl ExecutionContext

pub fn database_identity(&self) -> Identity

Returns the identity of the database on which we are operating.

pub fn reducer_name(&self) -> &str

If this is a reducer context, returns the name of the reducer.

pub fn into_reducer_name(self) -> String

If this is a reducer context, returns the name of the reducer.

pub fn reducer_context(&self) -> Option<&ReducerContext>

If this is a reducer context, returns the full reducer metadata.

pub fn workload(&self) -> WorkloadType

Returns the type of workload that is being executed.

Trait Implementations

impl Clone for ExecutionContext

fn clone(&self) -> ExecutionContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.
