Trait MaybeConvert

Source 
pub trait MaybeConvert<A, B> {
    // Required method
    fn maybe_convert(a: A) -> Option<B>;
}
Expand description

Fallible conversion trait returning an Option. Generic over both source and destination types.

Required Methods§

Source

fn maybe_convert(a: A) -> Option<B>

Attempt to make conversion.

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.
