Trait ParamValue 

pub trait ParamValue<'a> {
    // Required method
    fn as_value(&self) -> Cow<'a, str>;
}

A trait representing a parameter value.

Required Methods

fn as_value(&self) -> Cow<'a, str>

The parameter value as a string.

Dyn Compatibility

This trait is dyn compatible.

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