Struct Vec4u

pub struct Vec4u(/* private fields */);

A 4-component non-owning view of an unsigned Euclidean vector.

Guarantees

This type has the strict requirement that it can only reference a 4-component slice of u32 values. It is guaranteed to never refer to more or less than 4 entries.

Relation to Vector4u

Vec4u is a non-owning equivalent of Vector4u. This enables non-vector types to either Deref or provide conversion-related utilities into Vec4u types to be able to access and benefit from vector operations.

Implementations

impl Vec4u

pub const fn from_array(array: &[u32; 4]) -> &Self

Forms a reference to a Vec4u from a 4-component u32 array.

This function is identical to from_slice_unchecked, except it is not marked unsafe.

Parameters

• array - an array containing 4 u32 values.

Examples

Basic use:

let array: [u32; 4] = [1, 42, 314, 9];

let vec = Vec4u::from_array(&array);

assert_eq!(vec.as_ptr(), array.as_ptr());
assert_eq!(vec.x(), array[0]);
assert_eq!(vec.y(), array[1]);
assert_eq!(vec.z(), array[2]);
assert_eq!(vec.w(), array[3]);

pub fn from_mut_array(array: &mut [u32; 4]) -> &mut Self

Forms a mutable reference to a Vec4u from a 4-component u32 array.

This function is identical to from_mut_slice_unchecked, except it is not marked unsafe.

Parameters

• array - an array containing 4 u32 values.

Examples

Basic use:

let mut array: [u32; 4] = [1, 420, 314, 9];

let vec = Vec4u::from_mut_array(&mut array);

assert_eq!(vec.as_ptr(), array.as_ptr());

pub const fn from_slice(slice: &[u32]) -> Result<&Self, VecError>

Forms a reference to a Vec4u from a slice of u32.

This requires that slice.len() == 4, otherwise this returns VecError.

Parameters

• slice - the slice of u32s.

Examples

Basic use:

let slice = &[1, 42, 314, 9];

let vec = Vec4u::from_slice(slice).unwrap();

assert_eq!(vec.as_ptr(), slice.as_ptr());
assert_eq!(vec.x(), slice[0]);
assert_eq!(vec.y(), slice[1]);
assert_eq!(vec.z(), slice[2]);
assert_eq!(vec.w(), slice[3]);

Invalid size:

let slice = &[1];

let vec = Vec4u::from_slice(slice);

assert!(vec.is_err());

pub fn from_mut_slice(slice: &mut [u32]) -> Result<&mut Self, VecError>

Forms a mutable reference to a Vec4u from a mutable slice of u32.

This requires that slice.len() == 4, otherwise this returns VecError.

Parameters

• slice - the mutable slice of u32s.

Examples

Basic use:

let slice = &mut [1, 42, 314, 9];

let vec = Vec4u::from_mut_slice(slice).unwrap();

assert_eq!(vec.as_ptr(), slice.as_ptr());

Invalid size:

let slice = &mut [1];

let vec = Vec4u::from_mut_slice(slice);

assert!(vec.is_err());
