cratestack-sqlite 0.7.5

//! cratestack#398 regression test: a schema field named after a Rust
//! keyword used to make `include_embedded_schema!` (and
//! `include_server_schema!`) emit uncompilable Rust — the generated struct
//! field was written verbatim, with no raw-identifier (`r#`) escaping.
//!
//! This is the real reproduction from the issue: before the fix, this
//! file failed to compile at all, with `rustc` pointing at the
//! `include_embedded_schema!` line below rather than at any one field.
//! After the fix, `cratestack_macros::shared::ident` escapes every
//! keyword-named field as a raw identifier at every emission site (struct
//! field, `FromRow`/row-decode, `FieldRef` accessor, client struct), so
//! this compiles and round-trips like any other field.
//!
//! `self`/`Self`/`super`/`crate` are deliberately not included here — the
//! parser now rejects those outright at schema-parse time (no raw
//! identifier form exists for them at all); see
//! `cratestack_parser::tests_reserved_keywords`.
//!
//! The fixture's model is named `KeywordField` (singular), not
//! `KeywordFields` — table/route naming is
//! `pluralize(to_snake_case(model.name))`, and `pluralize` is a naive
//! "append s, or es if it already ends in s" (see
//! `cratestack_core::route_naming::pluralize`), so a model already ending
//! in `s` would double-pluralize (`keyword_fieldses`). Nothing to do with
//! this issue — just avoided for a cleaner fixture.
