Struct rin::math::VecStorage

#[repr(C)]
pub struct VecStorage<N, R, C> where
    C: Dim,
    R: Dim,  { /* fields omitted */ }

A Vec-based matrix data storage. It may be dynamically-sized.

Implementations

impl<N, R, C> VecStorage<N, R, C> where
    C: Dim,
    R: Dim, 

pub fn new(nrows: R, ncols: C, data: Vec<N, Global>) -> VecStorage<N, R, C>

Creates a new dynamic matrix data storage from the given vector and shape.

pub fn as_vec(&self) -> &Vec<N, Global>

The underlying data storage.

pub unsafe fn as_vec_mut(&mut self) -> &mut Vec<N, Global>

The underlying mutable data storage.

This is unsafe because this may cause UB if the size of the vector is changed by the user.

pub unsafe fn resize(self, sz: usize) -> Vec<N, Global>

Resizes the underlying mutable data storage and unwraps it.

If sz is larger than the current size, additional elements are uninitialized. If sz is smaller than the current size, additional elements are truncated.

pub fn len(&self) -> usize

The number of elements on the underlying vector.

pub fn is_empty(&self) -> bool

Returns true if the underlying vector contains no elements.
