1//! The `resolver` module contains the definitions and implementations for the internal
2//! `ResolveValue` and `WriteValue` traits. The former converts AST nodes to a
3//! [`FluentValue`], and the latter converts them to a string that is written to an
4//! implementor of the [`std::fmt::Write`] trait.
