# query.private.Predicate

- **Module:** query.private
- **Package:** libtmux
- **Language:** Rust
- **Kind:** struct
- **Source:** https://github.com/libtmux/libtmux-rs/blob/8a648c0894dfffc9303583f753b6c8ae01f2fe76/crates/libtmux/src/query/private.rs#L82

One opaque predicate passed to generated candidate dispatch.

Downstream code can inspect only the stable field name and call the
typed matching or validation helpers.

The [`crate::query::Filterable`] example executes every scalar helper
through a hand-written generated-code expansion.
