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.

## Associated Types

### `type Error`

The type returned in the event of a conversion error.

## 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`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
