Trait rutie::TryConvert

pub trait TryConvert<T>: Sized {
    type Nil;
    fn try_convert(value: T) -> Result<Self, Self::Nil>;
}

Implicit conversion or nil.

This is meant for “implicit conversions” much like Ruby's:

• Array.try_convert
• Hash.try_convert
• String.try_convert
• Regexp.try_convert
• IO.try_convert

This is NOT Rust object to Rust object casting for Ruby objects like try_convert_to<T> is.

Associated Types

type Nil

The type returned in the event of a conversion error.

Required Methods

fn try_convert(value: T) -> Result<Self, Self::Nil>

Performs the conversion.

• impl TryConvert<AnyObject> for RString type Nil = NilClass;
