Trait Eval 

pub trait Eval {
    type Output;

    // Required method
    fn eval(self, vm: &mut Vm<'_>) -> SourceResult<Self::Output>;
}

Evaluate an expression.

Required Associated Types

type Output

The output of evaluating the expression.

Required Methods

fn eval(self, vm: &mut Vm<'_>) -> SourceResult<Self::Output>

Evaluate the expression to the output value.

Dyn Compatibility

This trait is dyn compatible.

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