pub trait TryInto<T> { type Err; fn try_into(self) -> Result<T, Self::Err>; }
An attempted conversion that consumes self
, which may or may not be expensive.
Library authors should not directly implement this trait, but should prefer implementing the TryFrom
trait, which offers greater flexibility and provides an equivalent TryInto
implementation for free, thanks to a blanket implementation in the standard library.
type Err
The type returned in the event of a conversion error.
fn try_into(self) -> Result<T, Self::Err>
Performs the conversion.
impl<T, U> TryInto<U> for T where U: TryFrom<T>
