Trait winnow::stream::Accumulate

pub trait Accumulate<T>: Sized {
    // Required methods
    fn initial(capacity: Option<usize>) -> Self;
    fn accumulate(&mut self, acc: T);
}

Abstracts something which can extend an Extend. Used to build modified input slices in escaped_transform

Required Methods

fn initial(capacity: Option<usize>) -> Self

Create a new Extend of the correct type

fn accumulate(&mut self, acc: T)

Accumulate the input into an accumulator

Object Safety

This trait is not object safe.
