Struct ChannelPaddingInstructions 

Source 
pub struct ChannelPaddingInstructions { /* private fields */ }
Expand description

Initial, and, overall, padding instructions for channels

This is used both to generate the initial instructions, and to handle updates: when used for handling updates, it contains the last instructions that has been implemented.

Central code managing all channels will contain a ChannelPaddingInstructions, and use ChannelPaddingInstructionsUpdatesBuilder to both update those Instructions and generate ChannelPaddingInstructionsUpdates messages representing the changes.

The channel frontend (methods on Channel) processes ChannelPaddingInstructionsUpdates from the channel manager, possibly into channel-specific updates.

Default is a placeholder to use pending availability of a netdir etc.

Implementations§

Source§

impl ChannelPaddingInstructions

Source

pub fn initial_update(&self) -> Option<ChannelPaddingInstructionsUpdates>

Create an update message which sets settings in self which are not equal to the initial behaviour of the reactor.

Used during channel startup.

Source§

impl ChannelPaddingInstructions

Source

pub fn start_update(&mut self) -> ChannelPaddingInstructionsUpdatesBuilder<'_>

Start building an update to channel padding instructions

The builder must not be dropped, once created; instead, finish must be called. So prepare your new values first, perhaps fallibly, and only then create and use the builder and send the update, infallibly.

(This is because the builder uses self: ChannelPaddingInstructions to track which values have changed, and the values in self are updated immediately by the field update methods.)

§Panics

ChannelPaddingInstructionsUpdatesBuilder panics if it is dropped.
