Trait TryFromParam

pub trait TryFromParam: Sized {
    // Required method
    fn try_from_param(param: &str) -> Option<Self>;
}

Fallible conversion between a param capture into a value.

Implemented for all types that implement FromStr by default.

Required Methods

fn try_from_param(param: &str) -> Option<Self>

Creates a new value of this type from the given param. Returns None if the param cannot be converted into a value of this type.

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.
