[][src]Struct nalgebra::base::VecStorage

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

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

Methods

impl<N, R: Dim, C: Dim> VecStorage<N, R, C>
[src]

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

The underlying data storage.

The underlying mutable data storage.

This is unsafe because this may cause UB if the vector is modified by the user.

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.

Methods from Deref<Target = Vec<N>>

Returns the number of elements the vector can hold without reallocating.

Examples

let vec: Vec<i32> = Vec::with_capacity(10);
assert_eq!(vec.capacity(), 10);

Extracts a slice containing the entire vector.

Equivalent to &s[..].

Examples

use std::io::{self, Write};
let buffer = vec![1, 2, 3, 5, 8];
io::sink().write(buffer.as_slice()).unwrap();

Returns the number of elements in the vector, also referred to as its 'length'.

Examples

let a = vec![1, 2, 3];
assert_eq!(a.len(), 3);

Returns true if the vector contains no elements.

Examples

let mut v = Vec::new();
assert!(v.is_empty());

v.push(1);
assert!(!v.is_empty());
