ExecuteContext

Struct ExecuteContext 

Source
pub struct ExecuteContext<'a> { /* private fields */ }
Expand description

Execution context for the expression VM.

Holds row views, correlated context, parameters and the request-local durable function dispatcher. It owns no query or transaction semantics.
