"Small vector" optimization for Rust: store up to a small number of items on the stack
|
|
|
|
## Example
|
|
|
|
```rust
|
|
use smallvec::{SmallVec, smallvec};
|
|
|
|
// This SmallVec can hold up to 4 items on the stack:
|
|
let mut v: SmallVec<[i32; 4]> = smallvec![1, 2, 3, 4];
|
|
|
|
// It will automatically move its contents to the heap if
|
|
// contains more than four items:
|
|
v.push(5);
|
|
|
|
// SmallVec points to a slice, so you can use normal slice
|
|
// indexing and other methods to access its contents:
|
|
v[0] = v[1] + v[2];
|
|
v.sort();
|
|
```
