Struct ContextResolver 

pub struct ContextResolver {
    pub vocab: Option<String>,
    pub prefixes: HashMap<String, String>,
    pub terms: HashMap<String, TermDef>,
}

A resolved JSON-LD context that maps short terms to full IRIs.

Fields

vocab: Option<String>

@vocab — default IRI prefix for unmapped terms

prefixes: HashMap<String, String>

prefix:suffix mappings (e.g., “oo” -> “https://…#”)

terms: HashMap<String, TermDef>

Direct term mappings (e.g., “Class” -> TermDef { iri, type_coercion })

Implementations

impl ContextResolver

pub fn new() -> Self

pub fn from_context_value( context_value: &Value, known_contexts: &HashMap<String, Value>, ) -> Result<Self>

Parse a JSON-LD @context value and build the resolver. known_contexts maps context IRIs to their parsed JSON content (from ModuleState.contexts).

pub fn expand_term(&self, term: &str) -> String

Expand a compacted term to a full IRI. E.g., “Class” -> “oo:Class” -> “https://…#Class” Or “oo:Class” -> “https://…#Class” Handles chained prefixes like “clv:x” -> “npmd:pkg/x” -> “https://…/pkg/x”

pub fn compact_iri(&self, iri: &str) -> String

Compact a full IRI back to a prefixed form. Returns the shortest representation: tries exact term matches first, then prefix matches, then @vocab, falling back to the original IRI.

impl Default for ContextResolver

fn default() -> ContextResolver

Returns the “default value” for a type.
