//! # Dispatch Rules
//!
//! This module provides the [`DispatchRule`] trait and supporting types for value-to-type
//! matching and conversion.
//!
//! [`DispatchRule`] is used by benchmark implementations to match runtime enum values
//! (e.g., `DataType::Float32`) to static Rust types (e.g., `Type<f32>`), enabling
//! type-driven overload resolution.

pub use api::{
    Description, DispatchRule, FailureScore, MatchScore, TaggedFailureScore, Why,
    IMPLICIT_MATCH_SCORE,
