//! Request schema consumed by the allocation-free native-client codec.
//!
//! The allocation-free codec expands this table for request type IDs, tag
//! rules, encoding, and size arithmetic. A cross-codec test checks the result
//! against the owned Deku codec.
//!
//! Each row is
//!
//! ```text
//! Variant, TYPE_ID_CONST, tag rule, { field: kind, ... };
//! ```
//!
//! The tag rule is `notag` for `Tversion`, which must use [`NOTAG`], and `tag`
//! for everything else, which must not. Field kinds:
//!
//! - `u8`, `u16`, `u32`, `u64`: fixed-width little-endian scalars
//! - `str`: `u16` length prefix followed by that many bytes
//! - `names`: `u16` count followed by that many `str`
//! - `payload`: `u32` count followed by that many bytes, always last
//! - `envelope`: the ZeroFS mutation envelope, always first
//!
//! [`NOTAG`]: crate::slice_codec::NOTAG

/// Expand `$emit` over every row. See the module docs for the row shape.
