method iter.sortBy

Stable ascending sort by key (a barrier: the whole input is pulled at the first pull).

Example:

oxl✓ checked in CI

fn main() io {
  print("{["fig", "apple", "kiwi"].iter().sortBy(s => s.len()).collect()}")
}

Output

["fig", "kiwi", "apple"]

pub(api) move fn sortBy<K: Ord, effect F>(key: fn(T) -> K F escaping) -> iter<T>  F

Complexity. O(n log n); the whole input is pulled at the first pull.

Since. 1.0.0-beta

Parameters

Name	Type
`key`	`fn(T) -> K F escaping`

iter<T> F
