Struct RdfMemory 

pub struct RdfMemory {
    pub total_bytes: usize,
    pub triple_count: usize,
    pub triples_and_indexes_bytes: usize,
    pub term_dictionary_bytes: usize,
    pub ring_index_bytes: usize,
    pub named_graph_count: usize,
}

RDF triple store memory breakdown.

Default is empty (all zeros) when the triple-store feature is disabled, so users on LPG-only builds see no RDF line in the hierarchical report.

Fields

total_bytes: usize

Total estimated RDF memory in bytes.

triple_count: usize

Number of triples across the default graph and any named graphs.

triples_and_indexes_bytes: usize

Primary triple set and all six index maps (subject, predicate, object, SP, PO, OS).

term_dictionary_bytes: usize

Cached term dictionary bytes (None when no cache is warm).

ring_index_bytes: usize

Cached Ring index bytes (only populated when ring-index is enabled).

named_graph_count: usize

Named graphs in the default store (does not include nested graph memory, which is summed into triples_and_indexes_bytes).

Implementations

impl RdfMemory

pub fn is_empty(&self) -> bool

True when no RDF memory is reported. Used by skip_serializing_if so LPG-only builds don’t emit an empty rdf block in JSON.

pub fn compute_total(&mut self)

Recomputes total_bytes from child values.

Trait Implementations

impl Clone for RdfMemory

fn clone(&self) -> RdfMemory

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RdfMemory

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for RdfMemory

fn default() -> RdfMemory

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RdfMemory

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for RdfMemory

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
