Trait FromValue 

pub trait FromValue<'a, 'b>: Sized {
    // Required method
    fn from_value(
        value: &'b str,
        position: &'b Position<'a>,
    ) -> Result<'a, Self>;
}

Required Methods

fn from_value(value: &'b str, position: &'b Position<'a>) -> Result<'a, Self>

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.
