Interface VariableResolver

cel/src/context.rs:285–287

VariableResolver implements a custom resolver for variables that is consulted before looking at variables added to the context. This allows dynamic variables, or avoiding HashMap lookup/creation. # Example ``` struct ValueContext { request: cel::Value, response: cel::Value, } impl cel::context::VariableResolver for ValueContext { fn resolve(&self, variable: &str) -> Option { match v

/// }
/// ```
pub trait VariableResolver: Send + Sync {
    fn resolve(&self, variable: &str) -> Option<Value>;
}

impl<T: VariableResolver> VariableResolver for Box<T> {
    fn resolve(&self, variable: &str) -> Option<Value> {
