Module types 

TypeScript type generation and collection.

This module handles:

• Collecting named types (structs and enums) from service definitions
• Generating TypeScript type definitions (interfaces, type unions)
• Converting Rust types to TypeScript type strings

Functions

collect_named_types

Collect all named types (structs and enums with a name) from a service. Returns a vector of (name, Shape) pairs in dependency order.

generate_named_types

Generate TypeScript type definitions for all named types.

is_fully_supported

Check if a type can be fully encoded/decoded. Channel types (Tx/Rx) are supported - they encode as channel IDs.

ts_field_access

Generate TypeScript field access expression. Uses bracket notation for numeric field names (tuple fields), dot notation otherwise.

ts_scalar_type

Convert ScalarType to TypeScript type string.

ts_type

TypeScript type for user-facing type definitions. Uses named types when available.

ts_type_base_named

Convert Shape to TypeScript type string, using named types when available. This handles container types recursively, using named types at every level.

ts_type_client_arg

Convert Shape to TypeScript type string for client arguments. Schema is from server’s perspective - no inversion needed. Client passes the same types that server receives.

ts_type_client_return

Convert Shape to TypeScript type string for client returns. Schema is from server’s perspective - no inversion needed.

ts_type_server_arg

Convert Shape to TypeScript type string for server/handler arguments. Schema is from server’s perspective - no inversion needed. Rx means server receives, Tx means server sends.

ts_type_server_return

Schema is from server’s perspective - no inversion needed.
