Struct AbiBuffer 

pub struct AbiBuffer<T: 'static> { /* private fields */ }

A helper structure used with a stream to handle the canonical ABI representation of lists and track partial writes.

This structure is returned whenever a write to a stream completes. This keeps track of the original buffer used to perform a write (Vec<T>) and additionally tracks any partial writes. Writes can then be resumed with this buffer again or the partial write can be converted back to Vec<T> to get access to the remaining values.

This value is created through the StreamWrite future’s return value.

Implementations

impl<T: 'static> AbiBuffer<T>

pub fn into_vec(self) -> Vec<T>

Converts this AbiBuffer<T> back into a Vec<T>

This commit consumes this buffer and yields back unwritten values as a Vec<T>. The remaining items in Vec<T> have not yet been written and all written items have been removed from the front of the list.

Note that the backing storage of the returned Vec<T> has not changed from whe this buffer was created.

Also note that this can be an expensive operation if a partial write occurred as this will involve shifting items from the end of the vector to the start of the vector.

pub fn remaining(&self) -> usize

Returns the number of items remaining in this buffer.

Trait Implementations

impl<T> Drop for AbiBuffer<T>

fn drop(&mut self)

Executes the destructor for this type.
