Struct CacheState 

pub struct CacheState {
    pub cached_prefix_len: usize,
    /* private fields */
}

Tracks the cache lifecycle across turns.

Call advance_turn once per turn to get the appropriate CacheHint. Call reset when the adapter reports a cache miss so the next turn re-sends a Write.

Fields

cached_prefix_len: usize

Number of tokens in the cached prefix (set after annotation).

Implementations

impl CacheState

pub const fn new() -> Self

Create a new cache state (first turn will emit Write).

pub const fn advance_turn(&mut self, config: &CacheConfig) -> CacheHint

Advance the turn counter and return the cache hint for this turn.

• First turn (or after reset/refresh): returns Write { ttl }.
• Subsequent turns within cache_intervals: returns Read.
• After cache_intervals turns: returns Write (refresh).

pub const fn reset(&mut self)

Reset the cache state, forcing the next turn to emit Write.

Called when the adapter reports a provider cache miss.
