Trait ToConstValue 

pub trait ToConstValue: Sized {
    // Required method
    fn to_const_value(self) -> Result<ConstValue, RuntimeError>;
}

Trait to perform a conversion to a ConstValue.

Required Methods

fn to_const_value(self) -> Result<ConstValue, RuntimeError>

Convert into a constant 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.
