Implements a fixed-capacity stack-allocated Vec alternative backed by an array, using const generics.
Note: the word "static" here is meant by the traditional definition of "unchanging" / "not dynamic" etc.
This crate does not use literal static
variables for anything.
Fully #![no_std]
compatible (with almost no loss of functionality) by setting
default-features = false
for the staticvec
dependency in your Cargo.toml
.
Optional support for serialization and deserialization of the StaticVec
struct
via serde
is available by activating the serde_support
feature.
Contributions/suggestions/etc. very welcome!
Minimum supported Rust version: due to the use of const generics, this is a nightly-only crate at the moment.
Known issues: Incremental linking is, currently, an acknowledged cause of "internal compiler errors" when used
in conjunction with const generics. If you encounter any while trying to use this crate, there's a relatively good chance
they can be worked around by setting incremental = false
for the relevant build profile in your Cargo.toml
.
A basic usage example:
use staticvec::*;
fn main() {
let mut v = StaticVec::<i32, 64>::new();
for i in 0..v.capacity() {
v.push(i as i32);
}
for i in &v {
println!("{}", i);
}
v.clear();
v.insert(0, 47);
v.insert(1, 48);
v.insert(2, 49);
v.insert(v.len() - 1, 50);
v.insert(v.len() - 2, 51);
v.insert(v.len() - 3, 52);
for i in &v {
println!("{}", i);
}
for i in &v.reversed().drain(2..4) {
println!("{}", i);
}
while v.is_not_empty() {
println!("{}", v.remove(0));
}
for f in staticvec![12.0, 14.0, 15.0, 16.0].iter().skip(2) {
println!("{}", f);
}
for v in &staticvec![
staticvec![12.0, 14.0],
staticvec![16.0, 18.0],
staticvec![20.0, 22.0],
staticvec![24.0, 26.0]
] {
for f in v.iter().skip(1) {
println!("{}", f);
}
}
}
