    cache: LruCache<String, ()>,
}

Fields

cache: LruCache<String, ()>

Implementations

impl PoisonSet

pub fn new(capacity: usize) -> Self

pub fn key(tool: &str, selector: &str) -> String

The key for a tool call. \u{1} cannot appear in a tool name and is vanishingly unlikely in a selector, so it is a safe separator (avoids tool="a", sel="b" colliding with tool="a b").

pub fn insert(&mut self, tool: &str, selector: &str)

Record a poison key (marks it terminal). Touches LRU recency.

pub fn contains(&mut self, tool: &str, selector: &str) -> bool

True if this exact (tool, selector) is known-poison. Touches recency so hot poisons stay.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool
