Struct SemanticRegistry 

pub struct SemanticRegistry { /* private fields */ }

Implementations

impl SemanticRegistry

pub fn new() -> Self

pub fn begin_frame(&self)

Opens a frame, discarding everything the previous one published.

Without the discard, a frame that publishes nothing would still report the previous tree, and a test asserting that an element disappeared would pass against a stale snapshot.

pub fn generation(&self) -> u64

pub fn snapshot(&self) -> Snapshot

The tree published by the most recent completed frame.

pub fn global(cx: &App) -> Self

The registry components self-register into.

Panics when install has not run, because a missing registry would otherwise silently produce empty snapshots that tests read as passes.

pub fn try_global(cx: &App) -> Option<Self>
