Fabric type

Implementations

impl Fabric

pub fn mdns_service(&self) -> Option<MatterLocalService>

pub fn mdns_service_for(&self, node_id: u64) -> Option<MatterLocalService>

pub fn is_dest_id<C>( &self, crypto: C, random: &[u8], target: &[u8], ) -> Result<(), Error>

where C: Crypto,

Is the fabric matching the privided destination ID

pub fn compute_dest_id<C>( &self, crypto: C, random: &[u8], target_node_id: u64, out: &mut CryptoSensitive<rs_matter::::crypto::canon::Hash::{constant#0}>, ) -> Result<(), Error>

where C: Crypto,

Compute the destination identifier for a target node on this fabric.

Used by the CASE initiator to build Sigma1 (spec). destinationMessage = initiatorRandom || rootPublicKey || fabricId(LE) || nodeId(LE) destinationIdentifier = Crypto_HMAC(key=IPK, message=destinationMessage)

Arguments

• target_node_id: The node ID of the destination (peer) node, NOT the local node.

pub fn secret_key( &self, ) -> CryptoSensitiveRef<'_, rs_matter::::crypto::canon::CanonPkcSecretKeyRef::{constant#0}>

Return the secret key of the fabric

pub fn node_id(&self) -> u64

Return the fabric’s node ID

pub fn fabric_id(&self) -> u64

Return the fabric’s fabric ID

pub fn fab_idx(&self) -> NonZero<u8>

Return the fabric’s local index

pub fn compressed_fabric_id(&self) -> u64

Return the fabric’s compressed fabric ID

pub fn vendor_id(&self) -> u16

Return the fabric’s Vendor ID

pub fn label(&self) -> &str

Return the fabric’s label

pub fn root_ca(&self) -> &[u8]

Return the fabric’s Root CA in encoded TLV form

Use CertRef to decode on the fly

pub fn icac(&self) -> &[u8]

Return the fabric’s ICAC in encoded TLV form

Use CertRef to decode on the fly.

Note that this method might return an empty slice, which indicates that this fabric does not have an ICAC. (The shared icac_or_vvsc slot may instead hold a VVSC; see vvsc().)

pub fn noc(&self) -> &[u8]

Return the fabric’s NOC

pub fn ipk(&self) -> &KeySet

Return the fabric’s IPK

pub fn vvsc(&self) -> &[u8]

Return the fabric’s VVSC bytes (Matter Core spec). Empty when SetVIDVerificationStatement has never been called with a non-empty VVSC for this fabric, or when the fabric instead carries an ICAC (see icac()) — VVSC and ICAC share storage and are mutually exclusive per spec.

pub fn vid_verification_statement(&self) -> &[u8]

Return the fabric’s VID Verification Statement bytes (Matter Core spec). Either empty (not set) or exactly VID_VERIFICATION_STATEMENT_LEN bytes.

pub fn set_vid_verification( &mut self, vendor_id: Option<u16>, vid_verification_statement: Option<&[u8]>, vvsc: Option<&[u8]>, ) -> Result<(), Error>

Apply a SetVIDVerificationStatement mutation to the fabric. Each field is Some(slice) for “replace with this value” (where an empty slice clears the value), or None for “leave unchanged”. The caller is responsible for spec-level validation (size limits, VVSC vs ICAC mutual exclusion, “all fields absent” → INVALID_COMMAND, VendorID range, …); this method only enforces the storage invariants (heapless Vec capacity).

pub fn acl_iter(&self) -> impl Iterator<Item = &AclEntry>

Return an iterator over the ACL entries of the fabric

pub fn acl_add(&mut self, entry: AclEntry) -> Result<usize, Error>

Add a new ACL entry to the fabric.

Return the index of the added entry.

pub fn acl_add_init<I>(&mut self, init: I) -> Result<usize, Error>

where I: Init<AclEntry, Error>,

Add a new ACL entry to the fabric using the supplied initializer.

Return the index of the added entry.

pub fn acl_update(&mut self, idx: usize, entry: AclEntry) -> Result<(), Error>

Update an existing ACL entry in the fabric

pub fn acl_update_init<I>(&mut self, idx: usize, init: I) -> Result<(), Error>

where I: Init<AclEntry, Error>,

Update an existing ACL entry in the fabric using the supplied initializer

pub fn acl_remove(&mut self, idx: usize) -> Result<(), Error>

Remove an ACL entry from the fabric

pub fn acl_remove_all(&mut self)

Remove all ACL entries from the fabric

Trait Implementations

impl Debug for Fabric

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

Formats the value using the given formatter.

impl<'__from_tlv> FromTLV<'__from_tlv> for Fabric

fn from_tlv(element: &TLVElement<'__from_tlv>) -> Result<Fabric, Error>

Deserialize the type from a TLV-encoded element.

fn init_from_tlv(element: TLVElement<'__from_tlv>) -> impl Init<Fabric, Error>

Generate an in-place initializer for the type that initializes the type from a TLV-encoded element.

fn nullable_from_tlv(element: &TLVElement<'a>) -> Result<Self, Error>

Deserialize the type from a TLV-encoded element.

fn init_nullable_from_tlv(element: TLVElement<'a>) -> impl Init<Self, Error>

Generate an in-place initializer for the type that initializes the type from a TLV-encoded element.

impl ToTLV for Fabric

fn to_tlv<W>(&self, tag: &TLVTag, tw: W) -> Result<(), Error>

where W: TLVWrite,

Serialize the type to a TLV-encoded stream.

fn tlv_iter(&self, tag: TLVTag) -> impl Iterator<Item = Result<TLV<'_>, Error>>

Serialize the type as an iterator of TLV instances by potentially borrowing data from the type.

fn nullable_to_tlv<W>(&self, tag: &TLVTag, tw: W) -> Result<(), Error>

where W: TLVWrite,

Serialize the type to a TLV-encoded stream.

fn nullable_tlv_iter( &self, tag: TLVTag, ) -> impl Iterator<Item = Result<TLV<'_>, Error>>

Serialize the type as an iterator of TLV instances by potentially borrowing data from the type.

impl<'__from_tlv> TryFrom<&TLVElement<'__from_tlv>> for Fabric

type Error = Error

The type returned in the event of a conversion error.

fn try_from( element: &TLVElement<'__from_tlv>, ) -> Result<Fabric, <Fabric as TryFrom<&TLVElement<'__from_tlv>>>::Error>

Performs the conversion.
