Struct PredicateTemplate 

pub struct PredicateTemplate {
    pub name: String,
    pub type_params: Vec<String>,
    pub value_params: Vec<String>,
    pub body: PredicateBody,
}

A template for creating multiple similar predicates.

Templates allow defining patterns for predicates that can be instantiated with different domains or properties.

Fields

name: String

Template name

type_params: Vec<String>

Type parameters (e.g., [“T”, “U”])

value_params: Vec<String>

Value parameters (e.g., [“relation”])

body: PredicateBody

The body defining how to construct the predicate

Implementations

impl PredicateTemplate

pub fn new( name: impl Into<String>, type_params: Vec<String>, value_params: Vec<String>, body: PredicateBody, ) -> Self

Creates a new predicate template.

pub fn instantiate( &self, type_args: &[String], value_args: &[String], ) -> Result<CompositePredicate, AdapterError>

Instantiates this template with concrete types and values.
