core::convert::TryInto - Rust
Description: API documentation for the Rust `TryInto` trait in crate `core`.
Keywords: rust, rustlang, rust-lang, TryInto

# 1.34.0[−][src]Trait core::convert::TryInto

    pub trait TryInto<T>: Sized {
        type Error;
        fn try_into(self) -> Result<T, Self::Error>;
    }

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.
