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

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

Unstable (`try_from` #33417)

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.

## Associated Types

### `type Err`

Unstable (`try_from` #33417)

The type returned in the event of a conversion error.

## Required Methods

### `fn try_into(self) -> Result<T, Self::Err>`

Unstable (`try_from` #33417)

Performs the conversion.

## Implementors

- `impl<T, U> TryInto<U> for T where U: TryFrom<T>`

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
