Struct A2aFeatureProfile 

pub struct A2aFeatureProfile { /* private fields */ }

The per-revision capability bitset for an A2A peer.

The matrix is small (one row per known version, one column per Feature::ALL); the type holds it as a fixed-size [bool; N_FEATURES] so the matrix lives in the type system rather than in a HashMap that the feature set could silently diverge from.

Implementations

impl A2aFeatureProfile

pub const fn for_known_version(version: A2aVersion) -> Self

Build the profile for a known version. The matrix is the authoritative source; a per-version row is a literal here. A future revision adds a row, not a column.

pub const fn is_enabled(&self, feature: Feature) -> bool

true if the named feature is enabled. The match is on a fixed-size array indexed by the feature’s position in Feature::ALL; a new variant appended to ALL is the only edit the index needs to pick up.

pub const fn version(&self) -> A2aVersion

The version this profile was derived for. The dispatcher’s VersionNotSupportedError includes this so a peer that did not negotiate sees which version it landed on.
