1.0.0[][src]Module sgx_tstd::convert

Traits for conversions between types.

The traits in this module provide a way to convert from one type to another type. Each trait serves a different purpose:

The traits in this module are often used as trait bounds for generic functions such that to arguments of multiple types are supported. See the documentation of each trait for examples.

As a library author, you should always prefer implementing From<T> or TryFrom<T> rather than Into<U> or TryInto<U>, as From and TryFrom provide greater flexibility and offer equivalent Into or TryInto implementations for free, thanks to a blanket implementation in the standard library. When targeting a version prior to Rust 1.41, it may be necessary to implement Into or TryInto directly when converting to a type outside the current crate.

Generic Implementations

See each trait for usage examples.



The error type for errors that can never happen.



Supporting trait for inherent methods of f32 and f64 such as round_unchecked_to. Typically doesn’t need to be used directly.


Used to do a cheap mutable-to-mutable reference conversion.


Used to do a cheap reference-to-reference conversion.


Used to do value-to-value conversions while consuming the input value. It is the reciprocal of Into.


A value-to-value conversion that consumes the input value. The opposite of From.


Simple and safe type conversions that may fail in a controlled way under some circumstances. It is the reciprocal of TryInto.


An attempted conversion that consumes self, which may or may not be expensive.



The identity function.
