Struct DialogWatch 

pub struct DialogWatch { /* private fields */ }

The dialog event package (RFC 4235).

Holds one watcher’s view: the dialogs, and the version counter that view is up to.

Implementations

impl DialogWatch

pub fn new(entity: impl Into<String>) -> Self

A watch on this address of record.

pub fn package() -> &'static str

The Event package name.

pub fn version(&self) -> u32

The version the next document will carry.

pub fn document(&mut self, dialogs: &[Dialog]) -> String

The next document for this watcher.

The first is always full and the rest are partial (§4.1). A watcher that joined mid-call is given the whole picture once and told about changes after that; sending only changes from the start would leave it inferring a state nobody ever described.

The version is per subscription, not per resource (§4.1): two watchers of the same set of dialogs each count from zero, and sharing a counter would make one of them see gaps.

Trait Implementations

impl Debug for DialogWatch

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
