Module nstd_sys::vec

Available on crate feature nstd_vec only.

A dynamically sized contiguous sequence of values.

Structs

NSTDVec

A dynamically sized contiguous sequence of values.

Functions

nstd_vec_as_mut_ptr

Returns a pointer to a vector’s raw data.

nstd_vec_as_ptr

Returns a pointer to a vector’s raw data.

nstd_vec_as_slice

Returns an immutable slice containing all of a vector’s active elements.

nstd_vec_as_slice_mut

Returns a slice containing all of a vector’s active elements.

nstd_vec_cap

Returns a vector’s capacity.

nstd_vec_clear

Sets a vector’s length to zero.

nstd_vec_clone

Creates a new deep copy of vec.

nstd_vec_extend^⚠

Pushes a series of values onto a vector.

nstd_vec_free

Frees an instance of NSTDVec.

nstd_vec_from_slice^⚠

Creates a new vector from a slice.

nstd_vec_get

Returns an immutable pointer to the element at index pos in vec.

nstd_vec_get_mut

Returns a pointer to the element at index pos in vec.

nstd_vec_insert^⚠

Attempts to insert a value into a vector at index.

nstd_vec_len

Returns the length of a vector.

nstd_vec_new

Creates a new vector without allocating any resources.

nstd_vec_new_with_cap

Creates a new vector initialized with the given capacity.

nstd_vec_pop

Removes the last value of a vector and returns a pointer to it.

nstd_vec_push^⚠

Pushes a value onto a vector by copying bytes to the end of the vector’s buffer. The number of bytes to push is determined by vec’s stride.

nstd_vec_remove

Removes the element at index in a vector.

nstd_vec_reserve

Reserves some space on the heap for at least size more elements to be pushed onto a vector without making more allocations.

nstd_vec_shrink

Decreases a vector’s capacity to match it’s length.

nstd_vec_stride

Returns the amount of bytes each value in a vector occupies.

nstd_vec_truncate

Shortens a vector, keeping the first len elements.
