Struct CommandContext 

pub struct CommandContext {
    node: Arc<Node>,
    ui_sender: UnboundedSender<UIEvent>,
}

Provides context and utilities to command handlers.

This struct allows command handlers to interact with the core application Node and send events back to the user interface.

Fields

node: Arc<Node>

A reference to the application’s core Node.

ui_sender: UnboundedSender<UIEvent>

The sender for dispatching UIEvents to the UI.

Implementations

impl CommandContext

pub fn new(node: Arc<Node>, ui_sender: UnboundedSender<UIEvent>) -> Self

Creates a new CommandContext.

Arguments

• node - An Arc to the application’s core Node.
• ui_sender - An mpsc::UnboundedSender for UIEvents.

pub fn node(&self) -> &Arc<Node>

Returns a reference to the application’s core Node.

pub fn emit(&self, event: UIEvent)

Emits a generic UIEvent to the user interface.

Arguments

• event - The UIEvent to emit.

pub fn emit_chat<S: Into<String>>(&self, message: S)

Emits a chat message to be displayed in the UI.

Arguments

• message - The message content.

pub fn emit_history<S: Into<String>>(&self, message: S)

Emits a history output block to be displayed in the UI.

This is typically used for multi-line outputs from commands like history.

Arguments

• message - The history output content.
