Crate llkv_expr 

Shared expression utilities for building typed predicates over Arrow data.

The crate exposes three building blocks:

• expr defines a logical predicate AST that is independent of concrete Arrow scalar types.
• literal holds untyped literal values plus conversion helpers.
• typed_predicate turns logical operators into type-aware predicates that can be evaluated without additional allocations.

All modules are re-exported from the crate root so downstream users can pull the pieces they need with a single import.

Re-exports

pub use expr::*;

Modules

expr

Type-aware, Arrow-native predicate AST.

format

Formatting utilities for expression and predicate trees.

literal

Literal helpers are now provided by llkv-types. This module re-exports them for backward compatibility.

normalization

Expression normalization logic.

typed_predicate

Build and evaluate fully typed predicates derived from logical expressions.
