        node: TreeNode,

A mutable outboard.

This trait extends Outboard with methods to save a hash pair for a node and to set the length of the data file.

This trait can be used to incrementally save an outboard when receiving data. If you want to just ignore outboard data, there is a special placeholder outboard implementation super::outboard::EmptyOutboard.

Required Associated Types

type SaveFuture<'a>: Future<Output = Result<()>> where Self: 'a

Future returned by save

type SetSizeFuture<'a>: Future<Output = Result<()>> where Self: 'a

Future returned by set_size

Required Methods

fn save( &mut self, node: TreeNode, hash_pair: &(Hash, Hash) ) -> Self::SaveFuture<'_>

Save a hash pair for a node

fn set_size(&mut self, len: ByteNum) -> Self::SetSizeFuture<'_>

Set the length of the file for which this outboard is
