[−][src]Trait packed_simd::Cast

pub trait Cast<T>: Sized {
    fn cast(self) -> T;
}

Numeric cast from Self to T.

Note: This is a temporary workaround until the conversion traits specified > in RFC2484 are implemented.

Numeric cast between vectors with the same number of lanes, such that:

casting integer vectors whose lane types have the same size (e.g. i32xN -> u32xN) is a no-op,
casting from a larger integer to a smaller integer (e.g. u32xN -> u8xN) will truncate,
casting from a smaller integer to a larger integer (e.g. u8xN -> u32xN) will:
- zero-extend if the source is unsigned, or
- sign-extend if the source is signed,
casting from a float to an integer will round the float towards zero,
casting from an integer to float will produce the floating point representation of the integer, rounding to nearest, ties to even,
casting from an f32 to an f64 is perfect and lossless,
casting from an f64 to an f32 rounds to nearest, ties to even.

Required methods

Numeric cast from self to T.
