Type Alias MatrixViewMut4 

pub type MatrixViewMut4<'a, T, RStride = U1, CStride = U4> = Matrix<T, U4, U4, ViewStorageMut<'a, T, U4, U4, RStride, CStride>>;

A mutable column-major 4x4 matrix view.

See MatrixView4 for an immutable version of this type.

Because this is an alias, not all its methods are listed here. See the Matrix type too.

Aliased Type

#[repr(C)]
pub struct MatrixViewMut4<'a, T, RStride = U1, CStride = U4> {
    pub data: ViewStorageMut<'a, T, Const<4>, Const<4>, RStride, CStride>,
    /* private fields */
}

Fields

data: ViewStorageMut<'a, T, Const<4>, Const<4>, RStride, CStride>

The data storage that contains all the matrix components. Disappointed?

Well, if you came here to see how you can access the matrix components, you may be in luck: you can access the individual components of all vectors with compile-time dimensions <= 6 using field notation like this: vec.x, vec.y, vec.z, vec.w, vec.a, vec.b. Reference and assignation work too:

let mut vec = Vector3::new(1.0, 2.0, 3.0);
vec.x = 10.0;
vec.y += 30.0;
assert_eq!(vec.x, 10.0);
assert_eq!(vec.y + 100.0, 132.0);

Similarly, for matrices with compile-time dimensions <= 6, you can use field notation like this: mat.m11, mat.m42, etc. The first digit identifies the row to address and the second digit identifies the column to address. So mat.m13 identifies the component at the first row and third column (note that the count of rows and columns start at 1 instead of 0 here. This is so we match the mathematical notation).

For all matrices and vectors, independently from their size, individual components can be accessed and modified using indexing: vec[20], mat[(20, 19)]. Here the indexing starts at 0 as you would expect.
