- Fix ResourceContents enum to properly serialize with camelCase field names
- Add comprehensive tests to verify JSON serialization compliance
- Ensure all resource-related structs use mimeType as per MCP spec
- Add tests for RawResource, ResourceContents, RawImageContent, RawAudioContent
- Add test for prompt message image content serialization
- Update message schema files to reflect mimeType changes
- Fix import ordering to match project formatting standards
This change ensures the Rust SDK is fully compliant with the MCP specification
which requires mimeType (camelCase) for all resource content types.
* feat(model): add json schema generation support for all model types
This commit adds JSON Schema support for all model types by implementing
`schemars::JsonSchema` trait. The feature is gated behind the new
`schemars` feature flag. This enables automatic schema generation for
API documentation and validation purposes. Added tests to verify schema
generation for client and server JSON-RPC messages.
* fix(model): add manual json schema implementation for `NumberOrString`
This commit adds a manual implementation of `JsonSchema` trait for the
`NumberOrString` enum to properly represent its union type nature in
JSON Schema. The schema now correctly specifies that the type can be
either a number or a string using the `oneOf` validation keyword.
* fix(model): skip extensions field in json schema generation
The `Extensions` type was incorrectly included in JSON schema
generation, which could lead to confusing API documentation. This commit
adds `#[schemars(skip)]` attribute to all `extensions` fields in request
and notification structs, and removes the manual `JsonSchema`
implementation for the `Extensions` type since it's an internal
implementation detail that shouldn't be exposed in the schema.
