Implementations

source

impl<T, U> VecMappedInPlace<T, U>

source

fn new(vec: Vec<T>) -> Self

source

unsafe fn finish(self) -> Vec

Converts back into a Vec once the map is complete.

Trait Implementations

source

impl<T, U> Drop for VecMappedInPlace<T, U>

VecMappedInPlace drops everything but the element that was passed to map when it panicked or returned an error. Everything before that index in the vector has type U (it has been mapped) and everything after it has type T (it has not been mapped).
