Trait SourcePrimitive 

Source 
pub trait SourcePrimitive {
    // Required methods
    fn manifest(&self) -> &SourcePrimitiveManifest;
    fn produce(

}
Expand description

A source primitive that produces values for graph evaluation.

Statelessness is enforced at registration by manifest validation (SRC-8, state.allowed == false) and at runtime by capture/replay. Structural enforcement on top (derive macros, marker traits, newtype wrappers) was considered and rejected; see docs/ledger/decisions/rejected-structural-enforcement-of-statelessness.md.

Required Methods§

Source

fn manifest(&self) -> &SourcePrimitiveManifest

Source

fn produce( &self, parameters: &HashMap<String, ParameterValue>, ctx: &ExecutionContext, ) -> HashMap<String, Value>

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
