Module glean_ffi::upload::upload_result

Result values of attempted ping uploads encoded for FFI use.

These are exposed as C defines, e.g.:

#define UPLOAD_RESULT_RECOVERABLE 1
#define UPLOAD_RESULT_UNRECOVERABLE 2
#define UPLOAD_RESULT_HTTP_STATUS 0x8000

The language binding needs to replicate these constants exactly.

The HTTP_STATUS result can carry additional data (the HTTP response code). This is encoded in the lower bits.

The FFI layer can convert from a 32-bit integer (u32) representing the upload result (and associated HTTP response code) into the Glean-compatible UploadResult type.

These are defined in glean-core/src/upload/result.rs, but for cbindgen to also export them in header files we need to define them here as constants.

Inline tests ensure they match across crates.

Constants

UPLOAD_RESULT_HTTP_STATUS	A HTTP response code.
UPLOAD_RESULT_RECOVERABLE	A recoverable error.
UPLOAD_RESULT_UNRECOVERABLE	An unrecoverable error.
