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.

## Associated Types

#### type Error

[src]

The type returned in the event of a conversion error.

## Required methods

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

[src]

Performs the conversion.

## Implementors

### impl<T, U> TryInto<U> for T where
U: TryFrom<T>,

[src]

#### type Error = U::Error

#### fn try_into(self) -> Result<U, U::Error>
