Struct ToolWatcher 

pub struct ToolWatcher {
    pub start_id: u32,
    pub end_id: u32,
    pub start_name: String,
    pub end_name: String,
    /* private fields */
}

Stateful watcher for delimited regions in a token-ID stream.

Construct with a map and the names of the start/end specials. The watcher resolves them to IDs once and caches them — no further map access happens during ToolWatcher::feed.

Fields

start_id: u32

end_id: u32

start_name: String

end_name: String

Implementations

impl ToolWatcher

pub fn new( map: &TokenizerMap, start_name: &str, end_name: &str, ) -> Result<Self, ToolWatcherError>

pub fn inside(&self) -> bool

True while a region is open (start seen, end not yet).

pub fn reset(&mut self)

Drop any in-flight region buffer. Call between conversations so a leftover unclosed region from session N doesn’t spill into N+1.

pub fn feed(&mut self, ids: &[u32]) -> Vec<WatcherEvent>

Feed a chunk of token IDs and receive a flat list of events.

pub fn feed_i32(&mut self, ids: &[i32]) -> Vec<WatcherEvent>

Convenience: feed an i32 slice (the wire frame’s natural type from .NET surface familiarity). Internally upcast to u32.
