pub struct Sessions { /* private fields */ }

All sessions

Implementations

impl Sessions

pub const fn new() -> Sessions

Create a new Sessions instance.

pub fn init() -> impl Init<Sessions>

Create an in-place initializer for a new Sessions instance.

pub fn reset(&mut self)

impl Sessions

pub fn get_next_sess_id(&mut self) -> u16

pub fn get_next_exch_id<C>(&mut self, crypto: C) -> Result<u16, Error>

where C: Crypto,

pub fn get_session_for_eviction(&mut self) -> Option<&mut Session>

pub fn add( &mut self, msg_ctr: u32, reserved: bool, peer_addr: Address, peer_nodeid: Option<u64>, dev_det: &BasicInfoConfig<'_>, ) -> Result<&mut Session, Error>

pub fn remove(&mut self, id: u32) -> Option<Session>

This assumes that the higher layer has taken care of doing anything required as per the spec before the session is removed

pub fn remove_for_fabric( &mut self, fabric_idx: NonZero<u8>, expire_sess_id: Option<u32>, )

This assumes that the higher layer has taken care of doing anything required as per the spec before the sessions are removed or expired

pub fn get(&mut self, id: u32) -> Option<&mut Session>

pub fn iter(&self) -> impl Iterator<Item = &Session>

Iterate over the sessions

pub fn remove_pase(&mut self, expire_sess_id: Option<u32>)

Drop every PASE session, whether unpromoted (still SessionMode::Pase { fab_idx: 0 }) or already promoted to a fabric. Used by:

• RevokeCommissioning and a fail-safe expiry over a PASE session (Matter Core spec): when the commissioning window is torn down, any in-flight PASE sessions associated with it must be terminated. A PASE that was promoted via AddNOC is rolled back by the same fail-safe expiry, so its session must go too.
• CommissioningComplete (Matter Core spec): once the device transitions to operational state, all PASE sessions SHALL be terminated. Without this each commissioning round leaks the promoted PASE it ran on, and the session table eventually exhausts — visible as BUSY on the next round’s PBKDFParamRequest.

expire_sess_id is the optional ID of a session that should NOT be removed immediately — typically the session that issued the triggering command, so its response can still be sent. That session is marked as expired instead, so it stops accepting new exchanges but the in-flight one can complete; the transport reclaims the slot via the usual LRU eviction path.

Trait Implementations

impl Default for Sessions

fn default() -> Sessions

Returns the “default value” for a type.

impl Display for Sessions

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>
