Implementations

impl SessionKvLimits

The checks every store applies, in one place so a durable store refuses exactly what the in-memory one does.

pub fn check_key( &self, operation: &'static str, key: &[u16], ) -> Result<(), SessionKvError>

pub fn check_write( &self, key: &[u16], payload: &[u16], ) -> Result<(), SessionKvError>

The key and value checks set makes before looking at what the session holds.

pub fn check_capacity( &self, key: &[u16], payload: &[u16], held: SessionKvUsage, ) -> Result<u64, SessionKvError>

Whether set fits beside what the session already holds. The count bound only gates a new key. Returns the session’s retained bytes after the write.
