An array containing elements of type Element
Required Associated Types§
Required Methods§
Sourcefn len() -> usize
fn len() -> usize
Get the number of elements in the array type
use cgmath::prelude::*;
use cgmath::Vector3;
assert_eq!(Vector3::<f32>::len(), 3);Sourcefn from_value(value: Self::Element) -> Self
fn from_value(value: Self::Element) -> Self
Construct a vector from a single value, replicating it.
use cgmath::prelude::*;
use cgmath::Vector3;
assert_eq!(Vector3::from_value(1),
Vector3::new(1, 1, 1));Provided Methods§
Sourcefn as_mut_ptr(&mut self) -> *mut Self::Element
fn as_mut_ptr(&mut self) -> *mut Self::Element
Get a mutable pointer to the first element of the array.
Sourcefn swap_elements(&mut self, i: usize, j: usize)
fn swap_elements(&mut self, i: usize, j: usize)
Swap the elements at indices i and j in-place.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
