Trait FromArgument 

pub trait FromArgument<'a> {
    // Required method
    fn from_arg(arg: &'a str) -> Result<Self, FromArgumentError<'_>>
       where Self: Sized;
}

Required Methods

fn from_arg(arg: &'a str) -> Result<Self, FromArgumentError<'_>>

where Self: Sized,

Dyn Compatibility

This trait is dyn compatible.

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