Expand description
A contiguous growable array type with heap-allocated contents, written
Vec<T>
.
Vectors have O(1) indexing, amortized O(1) push (to the end) and O(1) pop (from the end).
Vectors ensure they never allocate more than isize::MAX
bytes.
§Examples
You can explicitly create a Vec
with Vec::new
:
…or by using the vec!
macro:
You can push
values onto the end of a vector (which will grow the vector
as needed):
Popping values works in much the same way:
Vectors also support indexing (through the Index
and IndexMut
traits):
