Rust Reference private_interfaces lint public function private type alias warning behavior

💡 Result:

The private_interfaces lint in Rust is designed to detect when an item's primary interface includes types that are more private than the item itself [1][2]. This includes situations where a public function uses a private type alias in its signature [3][4]. Key details regarding this behavior include: Reason for the Lint: Using a private type in a public interface creates a "type privacy" violation [5]. Because the private type cannot be named or accessed outside of its module, users of the public function would be unable to interact with the function's signature, effectively rendering the item unusable or leading to compilation errors [1][2]. Scope of "Primary Interface": The lint checks the "primary interface" of an item, which includes parameters and return types, but excludes generic bounds and where clauses [1][2]. Type Aliases and Visibility: - A private type alias is considered part of the item's signature [6][4]. If this alias is used in a public function's signature, the compiler warns (or errors, depending on settings) because the alias is not reachable from outside, preventing external consumers from referencing the full function signature [3][4]. - This behavior is consistent even if the private type alias resolves to a public type [7]. The lint is concerned with the visibility of the naming alias itself within the API contract [4]. Configuration and Behavior: - The private_interfaces lint is warn-by-default in the Rust compiler [5]. - It replaces older, more restrictive "private-in-public" compiler errors, providing a more modern framework for managing type privacy across module boundaries [3]. If you encounter this warning, the standard solution is to either make the type alias public (if it is intended to be part of your public API) or change the function signature to use a public type directly [5].

Citations:

Expose a public error type from process_scout_req_for_test.

The public method returns the pub(crate) alias crate::CarbideResult. Rust's warn-by-default private_interfaces lint flags this private alias in the method's return type, which can fail warning-as-error checks. Return Result<_, CarbideError> or make the alias public.

In `@crates/api-core/src/test_support/mod.rs` at line 73, Update
process_scout_req_for_test to expose a public return type by returning Result
with the public CarbideError directly, or make the CarbideResult alias public;
preserve the existing Action success type and error behavior while eliminating
the private_interfaces warning.
