Modules

backend_options

backend_trait

backends

overrides

provenance

The provenance header line every generated file carries, and the exact byte ordering it sits in.

resolve

sql_literal

Escape SQL text for safe splicing into a target-language string literal.

validation

Structs

GeneratedCode

NestedStructDef

One rendered nested-aggregate struct definition, paired with the name it declares so file writers can deduplicate.

NestedStructDegradation

One nested-aggregate column degrade_unsupported_nested_structs rewrote to a scalar JSON fallback because backend could not construct a real struct for it. See GeneratedCode::degraded_nested_structs for why this is surfaced at all rather than left as an internal rewrite (GH #147).

Functions

degrade_unsupported_nested_structs

generate

Backward-compatible: generate code using the default sqlx backend.

generate_single_enum_def

Backward-compatible: generate a single enum definition (sqlx backend). Uses the manifest directly for backward compatibility with existing callers.

generate_single_enum_def_with_backend

Generate a single enum definition using a specific backend.

generate_with_backend

Generate code using a specific backend.

generate_with_backend_and_overrides

Generate code using a specific backend with type overrides.

generate_with_backend_and_overrides_and_nested_composites

Generate code while promoting the named composites to their nested-capable form.

get_manifest_for_backend

Get the manifest for a backend. Defaults to PostgreSQL engine.

load_or_default_manifest

Backward-compatible: load the default sqlx manifest.

model_struct_name

The type name a SELECT * model is declared under and referenced by.

nested_type_is_emitted

Whether sql_name is reachable from a nested-aggregate struct the backend actually emitted a definition for.

singularize

Simple singularization: remove trailing ‘s’.

Type Aliases

DegradedNestedStructs

Degradation pass for nested-aggregate columns (json_agg(o.*), row_to_json(u.*)). Must run before resolve::resolve_columns – every caller that resolves AnalyzedColumns into a backend’s types needs this, not just generate_with_backend_and_overrides: scythe-cli’s RBS signature generation (generate_rbs_if_supported) calls resolve::resolve_columns directly on a second, independent path, so it must run this pass too or it silently bypasses the byte-identity guarantee for any backend that hasn’t opted in.
