# Module num_traits::cast [−] [src]

## Traits

AsPrimitive | A generic interface for casting between machine scalars with the `as` operator, which admits narrowing and precision loss. Implementers of this trait AsPrimitive should behave like a primitive numeric type (e.g. a newtype around another primitive), and the intended conversion must never fail.
FromPrimitive | A generic trait for converting a number to a value.
NumCast | An interface for casting between machine scalars.
ToPrimitive | A generic trait for converting a value to a number.

## Functions

cast | Cast from one machine scalar to another.

## 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`)
