Trait ActivationInterface

pub trait ActivationInterface<'f, Fm: FnMarker = ()> {
    // Required methods
    fn variables(&self) -> &VariableBindings<'f>;
    fn functions(&self) -> &FunctionBindings<'f>;
}

Interface for providing variable and function bindings during evaluation.

This trait defines the interface that activation types must implement to provide variable and function bindings to the CEL evaluator.

Type Parameters

• 'f - Lifetime of the functions in the bindings
• Fm - Function marker type indicating sync/async function support

Required Methods

fn variables(&self) -> &VariableBindings<'f>

Returns a reference to the variable bindings.

Variable bindings map variable names to their values during evaluation.

fn functions(&self) -> &FunctionBindings<'f>

Returns a reference to the function bindings.

Function bindings provide runtime function implementations that can override or supplement the functions registered in the environment.

Implementations on Foreign Types

impl ActivationInterface<'static> for &()

Empty activation implementation for references to the unit type.

fn variables(&self) -> &VariableBindings<'static>

fn functions(&self) -> &FunctionBindings<'static>

impl ActivationInterface<'static> for ()

Empty activation implementation for the unit type.

This allows you to use () as an activation when no variable or function bindings are needed.
