Struct ReadPath 

#[non_exhaustive]
pub struct ReadPath {
    pub endpoint: Option<u16>,
    pub cluster: Option<u32>,
    pub attribute: Option<u32>,
}

A read-request attribute path with optional (wildcard) components. A None field is omitted from the encoded AttributePathIB, which the Matter IM interprets as a wildcard (Appendix A.6): omit attribute → all attributes of the cluster; omit endpoint → all endpoints; etc. Responses are always keyed by a concrete AttributePath.

#[non_exhaustive]: a read/subscribe path may gain optional spec components (e.g. a data-version filter); marking it keeps such additions non-breaking. Build via ReadPath::concrete / ReadPath::cluster / ReadPath::all / ReadPath::new.

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.

endpoint: Option<u16>

Endpoint, or None for all endpoints.

cluster: Option<u32>

Cluster, or None for all clusters.

attribute: Option<u32>

Attribute, or None for all attributes.

Implementations

impl ReadPath

pub fn new( endpoint: Option<u16>, cluster: Option<u32>, attribute: Option<u32>, ) -> Self

A read path from raw optional components (a None component is a wildcard). Prefer Self::concrete / Self::cluster / Self::all for the common shapes.

pub fn concrete(endpoint: u16, cluster: u32, attribute: u32) -> Self

A concrete (endpoint, cluster, attribute) path (no wildcards).

pub fn cluster(endpoint: u16, cluster: u32) -> Self

All attributes of cluster on endpoint.

pub fn all() -> Self

Every attribute on every endpoint/cluster (full wildcard).
