Enum EngineLogicalTerm 

pub enum EngineLogicalTerm {
    Variable(String),
    Constant(String),
    Description(String),
    Unspecified,
    Number(f64),
}

A logical term — the typed representation of an FOL argument.

Variants

Variable(String)

A bound or free variable (e.g., Skolem variables, universally quantified vars).

Constant(String)

A ground constant (e.g., entity names from la).

Description(String)

An opaque description reference (from le determiner).

Unspecified

Unspecified placeholder (from zo'e).

Number(f64)

Numeric literal (from li + PA).

Implementations

impl LogicalTerm

pub fn display(&self) -> String

Human-readable rendering of a logical term (UI labels / witness display). Ported from the former nibli-protocol wire-term display.

pub fn trace_display(&self) -> String

Compact textual rendering used in CLI proof traces. Ported from the former nibli-protocol wire-term trace_display.
