Module emit_models 

Sigil-stitch emit for IR schemas (Rust models).

Each supported IrSchemaKind maps to one models/<name>.rs file.

Coverage:

• Object — struct with serde derives and #[serde(rename)] tags.
• Enum — Rust enum with serde rename per variant.
• Alias — pub type X = Y;
• Union — #[serde(untagged)] enum.
• Intersection — struct with #[serde(flatten)] fields.
• TaggedUnion — serde-tagged enum (internal/adjacent/external).

Functions

rust_type_str

rust_type_str_qualified
