Struct NodeListenerLocalBuilder

pub struct NodeListenerLocalBuilder<'a> { /* private fields */ }

A builder for registering node event callbacks.

Use Node::add_listener_local to create this and register callbacks that will be called when events of interest occur. After adding callbacks, use register to get back a NodeListener.

Examples

let node_listener = node.add_listener_local()
    .info(|info| println!("New node info: {info:?}"))
    .param(|seq, param_type, index, next, param| {
        println!("New node param: seq {seq}, param type {param_type:?}, index {index}, next {next}, param {:?}",
            param.map(Pod::as_bytes));
    })
    .register();

Implementations

impl<'a> NodeListenerLocalBuilder<'a>

pub fn info<F>(self, info: F) -> Self

where F: Fn(&NodeInfoRef) + 'static,

Set the node info event callback of the listener.

Callback parameters

info: Info about the node.

Examples

let node_listener = node.add_listener_local()
    .info(|info| println!("New node info: {info:?}"))
    .register();

pub fn param<F>(self, param: F) -> Self

where F: Fn(i32, ParamType, u32, u32, Option<&Pod>) + 'static,

Set the node param event callback of the listener.

This event is emitted as a result of enum_params or subscribe_params.

Callback parameters

seq: The sequence number of the request
param_type: The param type
index: The param index
next: The param index of the next param
param: The param

Examples

let node_listener = node.add_listener_local()
    .param(|seq, param_type, index, next, param| {
        println!("New node param: seq {seq}, param type {param_type:?}, index {index}, next {next}, param {:?}",
            param.map(Pod::as_bytes));
    })
    .register();

pub fn register(self) -> NodeListener

Subscribe to events and register any provided callbacks.
