Struct `ExtractIf`

struct ExtractIf<'a, T, F, A: Allocator = crate::alloc::Global> { ... }

An iterator which uses a closure to determine if an element should be removed.

This struct is created by Vec::extract_if. See its documentation for more.

Example

let mut v = vec![0, 1, 2];
let iter: std::vec::ExtractIf<'_, _, _> = v.extract_if(.., |x| *x % 2 == 0);
