Changelog

0.46.6

(fix): List- and set-typed path parameters are now joined instead of being interpolated directly, so a spec with an array path parameter produces an SDK that compiles.

Previously the parameter name was passed straight to format!, which does not compile because Vec<T> has no Display:

1
pub async fn path_array(&self, ids: &Vec<String>, ..) -> Result<Echo, ApiError> {
2
    &format!("params/path-array/{}", ids),

That is an E0277 in the generated crate, so the failure is not limited to the endpoint declaring the parameter — the whole SDK fails to build and every other endpoint in it becomes unusable.

The elements are now joined with a comma, which is OpenAPI’s default simple path style, using to_string() per element so that any Display element type works and not only String. Optional, nullable and map containers keep their previous behavior: an optional path parameter cannot be omitted from a path, and a map has no defined path serialization.

The non-default label (.a.b) and matrix (;ids=a,b) path styles remain unimplemented.

0.46.5

(fix): Aliases of unknown (e.g. AnyType wrapping serde_json::Value) now derive Default, so structs and aliases that contain them and derive Default compile without manual patching. The struct generator’s private copy of the default analysis has been folded into the shared hasDefaultImpl, which is now the single source of truth and no longer recurses forever on types that reference each other. #[serde(default)] emission is unchanged: a required unknown field still fails to deserialize when the key is missing.
