Trait CheckedConversion 

Source 
pub trait CheckedConversion {
    // Provided methods
    fn checked_from<T>(t: T) -> Option<Self>
       where Self: TryFrom<T> { ... }
    fn checked_into<T>(self) -> Option<T>
       where Self: TryInto<T> { ... }
}
Expand description

Convenience type to work around the highly unergonomic syntax needed to invoke the functions of overloaded generic traits, in this case TryFrom and TryInto.

Provided Methods§

Source

fn checked_from<T>(t: T) -> Option<Self>
where Self: TryFrom<T>,

Convert from a value of T into an equivalent instance of Option<Self>.

This just uses TryFrom internally but with this variant you can provide the destination type using turbofish syntax in case Rust happens not to assume the correct type.

Source

fn checked_into<T>(self) -> Option<T>
where Self: TryInto<T>,

Consume self to return Some equivalent value of Option<T>.

This just uses TryInto internally but with this variant you can provide the destination type using turbofish syntax in case Rust happens not to assume the correct type.

Dyn Compatibility§

This trait is dyn compatible.

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