Enum TryParse 

pub enum TryParse<T, P: PathType + ?Sized> {
    Success(T),
    Failure(Error<P::OwnedPath>),
}

A type that tries to parse a value of type T, but doesn’t fail if it can’t.

Instead, it keeps the original Error.

Variants

Success(T)

Successfully parsed a value of type T.

Failure(Error<P::OwnedPath>)

Failed to parse a value of type T.
