Trait TryInto

1.34.0 · Source

pub trait TryInto<T>: Sized {
    type Error;

    // Required method
    fn try_into(self) -> Result<T, Self::Error>;
}

Expand description

An attempted conversion that consumes self, which may or may not be expensive.

Library authors should usually not directly implement this trait, but should prefer implementing the TryFrom trait, which offers greater flexibility and provides an equivalent TryIntoimplementation for free, thanks to a blanket implementation in the standard library. For more information on this, see the documentation for Into.

This suffers the same restrictions and reasoning as implementingInto, see there for details.

This trait is not dyn compatible.
