Trait Parse 

pub trait Parse<'a>
where
    Self: Sized + Display,
{
    // Required methods
    fn parse(i: Arg<'a>) -> Result<Self, ParseErr<'a>>;
    fn desc() -> &'static str;
}

Required Methods

fn parse(i: Arg<'a>) -> Result<Self, ParseErr<'a>>

fn desc() -> &'static str

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.
