Struct ExtractionSchema 

pub struct ExtractionSchema {
    pub name: String,
    pub entity_types: BTreeMap<String, String>,
    pub relation_types: BTreeMap<String, RelationSpec>,
}

Extraction schema defining which entity types and relation types to extract.

Loaded from a ctxgraph.toml file or constructed via ExtractionSchema::default().

Fields

name: String

entity_types: BTreeMap<String, String>

relation_types: BTreeMap<String, RelationSpec>

Implementations

impl ExtractionSchema

pub fn load(path: &Path) -> Result<Self, SchemaError>

Load schema from a TOML file.

pub fn from_toml(content: &str) -> Result<Self, SchemaError>

Parse schema from a TOML string.

pub fn entity_labels(&self) -> Vec<&str>

Entity label strings for GLiNER input.

Returns the type key names (e.g. “Person”, “Database”). Suitable for models trained on those label conventions.

pub fn entity_label_descriptions(&self) -> Vec<(&str, &str)>

Entity descriptions for zero-shot GLiNER inference.

Returns (description, key) pairs. Passing the description as the label to GLiNER improves zero-shot recall because the model uses the label text as a natural-language prompt. The key is the canonical type name used in ExtractionSchema and benchmark fixtures.

pub fn entity_type_from_label<'a>(&'a self, label: &str) -> Option<&'a str>

Map a GLiNER class string back to the canonical entity type key.

When descriptions are used as labels, GLiNER returns the description as the span class. This method reverses that lookup.

pub fn relation_labels(&self) -> Vec<&str>

Relation label strings for GLiREL/relation extraction input.

Trait Implementations
