[][src]Struct cxx::CxxVector

#[repr(C, packed)]pub struct CxxVector<T> { /* fields omitted */ }

Binding to C++ std::vector<T, std::allocator<T>>.

Invariants

As an invariant of this API and the static analysis of the cxx::bridge macro, in Rust code we can never obtain a CxxVector by value. Instead in Rust code we will only ever look at a vector behind a reference or smart pointer, as in &CxxVector<T> or UniquePtr<CxxVector<T>>.

Implementations

impl<T> CxxVector<T> where
    T: VectorElement, 
[src]

pub fn len(&self) -> usize[src]

Returns the number of elements in the vector.

Matches the behavior of C++ std::vector<T>::size.

pub fn is_empty(&self) -> bool[src]

Returns true if the vector contains no elements.

Matches the behavior of C++ std::vector<T>::empty.

pub fn get(&self, pos: usize) -> Option<&T>[src]

Returns a reference to an element at the given position, or None if out of bounds.

pub unsafe fn get_unchecked(&self, pos: usize) -> &T[src]

Returns a reference to an element without doing bounds checking.

This is generally not recommended, use with caution! Calling this method with an out-of-bounds index is undefined behavior even if the resulting reference is not used.

Matches the behavior of C++ std::vector<T>::operator[].

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

Returns a slice to the underlying contiguous array of elements.

pub fn iter(&self) -> Iter<'_, T>[src]

Returns an iterator over elements of type &T.

Trait Implementations

impl<'a, T> IntoIterator for &'a CxxVector<T> where
    T: VectorElement, 
[src]

type Item = &'a T

The type of the elements being iterated over.

type IntoIter = Iter<'a, T>

Which kind of iterator are we turning this into?
