# Trait std::convert::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 `TryInto` implementation for free, thanks to a blanket implementation in the standard library. For more information on this, see the documentation for `Into`.

## Implementing `TryInto`

This suffers the same restrictions and reasoning as implementing `Into`, see there for details.
