Struct SemanticTag 

pub struct SemanticTag<'a> {
    pub mfg_code: Option<u16>,
    pub namespace_id: u8,
    pub tag: u8,
    pub label: Option<&'a str>,
}

A semantic tag describing an endpoint, as reported by Descriptor::TagList.

Matter Core spec 9.5 requires these to disambiguate endpoints that would otherwise be indistinguishable: when a node exposes two or more endpoints with the same device type under the same parent, each of them must carry a non-empty TagList, and no two of those lists may be identical. A certification harness enforces exactly that (TC_DESC_2_2).

Fields

mfg_code: Option<u16>

The manufacturer code scoping namespace_id, or None when the tag comes from a standard (CSA-defined) namespace.

namespace_id: u8

The namespace tag is drawn from.

tag: u8

The tag value within namespace_id.

label: Option<&'a str>

An optional human-readable label for the tag.

Implementations

impl<'a> SemanticTag<'a>

pub const fn new(namespace_id: u8, tag: u8) -> SemanticTag<'a>

Create a tag in a standard (CSA-defined) namespace, with no label.

pub const fn with_label(self, label: &'a str) -> SemanticTag<'a>

Attach a human-readable label to this tag.
