Trait 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

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
