Struct wasefire_board_api::Error
source · pub struct Error(/* private fields */);
Expand description
API errors.
Errors are equivalent to u32
but only using the 24 least significant bits: 8 bits for the
error space and 16 bits for the error code. The 8 most significant bits are zero. It is possible
to encode a Result<u32, Error>
into a i32
as long as the success value only uses the 31
least significant bits. Non-negative values encode success, while negative values encode the
error by taking its bitwise complement (thus setting the 8 most significant bits to 1).
Implementations§
source§impl Error
impl Error
sourcepub fn new(space: impl SpaceParam, code: impl CodeParam) -> Error
pub fn new(space: impl SpaceParam, code: impl CodeParam) -> Error
Creates a new error.
sourcepub fn decode(result: i32) -> Result<u32, Error>
pub fn decode(result: i32) -> Result<u32, Error>
Decodes a signed integer as a result (where errors are negative values).
§Panics
Panics if the signed integer is smaller than -16777216 (0xff000000).
