[][src]Struct fluence_it_types::ne_vec::NEVec

pub struct NEVec<T>(_)
where
    T: Debug
;

NEVec<T> represents a non-empty Vec<T>. It derefs to Vec<T> directly.

Implementations

impl<T> NEVec<T> where
    T: Debug
[src]

pub fn new(items: Vec<T>) -> Result<Self, EmptyVec>[src]

Creates a new non-empty vector, based on an inner Vec<T>. If the inner vector is empty, a EmptyVec error is returned.

pub fn into_vec(self) -> Vec<T>[src]

Converts this NEVec into Vec

Methods from Deref<Target = Vec<T>>

pub fn capacity(&self) -> usize1.0.0[src]

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);

pub fn as_slice(&self) -> &[T]1.7.0[src]

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();

pub fn as_ptr(&self) -> *const T1.37.0[src]

Returns a raw pointer to the vector's buffer.

The caller must ensure that the vector outlives the pointer this function returns, or else it will end up pointing to garbage. Modifying the vector may cause its buffer to be reallocated, which would also make any pointers to it invalid.

The caller must also ensure that the memory the pointer (non-transitively) points to is never written to (except inside an UnsafeCell) using this pointer or any pointer derived from it. If you need to mutate the contents of the slice, use as_mut_ptr.

Examples

let x = vec![1, 2, 4];
let x_ptr = x.as_ptr();

unsafe {
    for i in 0..x.len() {
        assert_eq!(*x_ptr.add(i), 1 << i);
    }
}

pub fn allocator(&self) -> &A[src]

🔬 This is a nightly-only experimental API. (allocator_api)

Returns a reference to the underlying allocator.

pub fn len(&self) -> usize1.0.0[src]

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);

pub fn is_empty(&self) -> bool1.0.0[src]

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());
