Trait swc_common::pass::util::move_map::MoveMap

pub trait MoveMap<T> {
    fn move_flat_map<F, I>(self, f: F) -> Self
    where
        F: FnMut(T) -> I,
        I: IntoIterator<Item = T>;

    fn move_map<F>(self, f: F) -> Self
    where
        F: FnMut(T) -> T,
    { ... }
}

Modifiers vector in-place.

Required methods

fn move_flat_map<F, I>(self, f: F) -> Self where
    F: FnMut(T) -> I,
    I: IntoIterator<Item = T>, 

This will be very slow if you try to extend vector using this method.

This method exists to drop useless nodes. You can return Option to do such shortening.

Provided methods

fn move_map<F>(self, f: F) -> Self where
    F: FnMut(T) -> T, 

Map in place.

Implementations on Foreign Types

impl<T> MoveMap<T> for Vec<T, Global>

pub fn move_map<F>(self, f: F) -> Vec<T, Global> where
    F: FnMut(T) -> T, 

This reduces binary size.

pub fn move_flat_map<F, I>(self, f: F) -> Vec<T, Global> where
    F: FnMut(T) -> I,
    I: IntoIterator<Item = T>,
