Struct FabricInfo 

#[non_exhaustive]
pub struct FabricInfo {
    pub fabric_id: u64,
    pub commissioner_node_id: u64,
    pub node_count: usize,
    pub icac_enabled: bool,
}

Metadata about a fabric the controller has created.

Returned by MatterController::fabrics so callers can check which fabrics already exist — in particular, before calling MatterController::create_fabric on every startup. Since issue #110, create_fabric refuses to create a second fabric with a fabric_id already present and returns Error::FabricAlreadyExists instead of silently duplicating it; fabrics() is how a caller checks first.

#[non_exhaustive]: more fields may be added without a breaking change.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

fabric_id: u64

Matter fabric identifier (spec §6.2.1).

commissioner_node_id: u64

The stable node ID the controller itself takes on this fabric — its own commissioner operational identity, minted once by crate::MatterController::create_fabric and reused for every CASE handshake on this fabric.

node_count: usize

Number of devices currently commissioned onto this fabric.

icac_enabled: bool

Whether this fabric uses a 3-tier RCAC->ICAC->NOC chain (true) or issues NOCs directly under the RCAC (false, the default from crate::FabricConfig::new).
