Trait ExpressionExt 

pub trait ExpressionExt {
    // Required methods
    fn map_resolve(
        &self,
        ctx: &mut Context<'_>,
    ) -> Result<Option<Value>, ExpressionError>;
    fn map_resolve_with_default<F>(
        &self,
        ctx: &mut Context<'_>,
        default_fn: F,
    ) -> Resolved
       where F: FnOnce() -> Value;
}

Required Methods

fn map_resolve( &self, ctx: &mut Context<'_>, ) -> Result<Option<Value>, ExpressionError>

fn map_resolve_with_default<F>( &self, ctx: &mut Context<'_>, default_fn: F, ) -> Resolved

where F: FnOnce() -> Value,

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
