Struct toolshed::list::ListBuilder

pub struct ListBuilder<'arena, T> { /* fields omitted */ }

A builder that allows one to push elements onto the end of the list.

This is in principle identical to GrowableList, however it skips some checks on pushing given that it always has to have at least one element, and thus might be ever so slightly faster.

Methods

impl<'arena, T: Copy> ListBuilder<'arena, T>

pub fn new(arena: &'arena Arena, first: T) -> Self

Create a new builder with the first element.

pub fn push(&self, arena: &'arena Arena, item: T)

Push a new item at the end of the List.

impl<'arena, T> ListBuilder<'arena, T>

pub fn as_list(&self) -> List<'arena, T>

Get a List from the builder.
