Struct CompositionValidator 

pub struct CompositionValidator { /* private fields */ }

Runtime composition validator backed by a loaded matrix.

Wraps a CompositionMatrix and provides efficient query methods for checking whether a given protocol×role×traffic_kind combination is supported, and what tier/evidence it has.

Implementations

impl CompositionValidator

pub fn load() -> Option<Self>

Load the composition matrix from the canonical path.

pub fn from_file(path: &Path) -> Result<Self, CompositionValidationError>

Load from an explicit file path.

pub fn query( &self, protocol: &str, role: &str, traffic_kind: &str, ) -> Option<&CompositionCell>

Query a single composition cell.

pub fn query_chain( &self, from_protocol: &str, to_protocol: &str, traffic_kind: &str, ) -> Option<&ChainComposition>

Query a chain composition.

pub fn is_supported( &self, protocol: &str, role: &str, traffic_kind: &str, ) -> bool

Check if a protocol+role+traffic_kind combination is supported (non-unsupported tier).

pub fn protocols_at_or_above_tier( &self, role: &str, traffic_kind: &str, min_tier: &str, ) -> Vec<&str>

Get all protocols supporting a given role+traffic_kind at or above a tier.

pub fn constraints_for(&self, protocol: &str) -> Vec<&CompositionConstraint>

Get all constraints that apply to a given protocol.

pub fn inner(&self) -> &CompositionMatrix

Return a reference to the inner matrix.
