Struct Mat4 

#[non_exhaustive]
pub struct Mat4 {
    pub m: [[f64; 4]; 4],
}

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

m: [[f64; 4]; 4]

Row-major: m[row][col]

Implementations

Trait Implementations

impl Clone for Mat4

fn clone(&self) -> Mat4

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Mat4

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Mat4

fn eq(&self, other: &Mat4) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
