Struct haiku::support::HaikuError

pub struct HaikuError { /* fields omitted */ }

This struct represents an Error for using this API

The error is very much based on the standard library's std::io::Error, and roughly has the same usage and functionality.

Methods

impl HaikuError

pub fn new<E>(kind: ErrorKind, error: E) -> HaikuError where
    E: Into<Box<dyn Error + Send + Sync>>, 

Create a new error with a kind, and a custom payload. The most common use is to attach a String that describes the error, but any struct that implements the std::error::Error trait will work.

pub fn last_os_error() -> HaikuError

Create a new error based on the last OS Error.

This function can be used to create an error after calling OS functions that set the global error number on failure.

pub fn from_raw_os_error(code: status_t) -> HaikuError

Convert a raw error constant to a HaikuError object

pub fn raw_os_error(&self) -> Option<status_t>

Convert the current error into a (lower level) Haiku error constant

pub fn kind(&self) -> ErrorKind

Get the ErrorKind for the current error

Trait Implementations

impl From<ErrorKind> for HaikuError

fn from(kind: ErrorKind) -> HaikuError

fn description(&self) -> &str

This method is soft-deprecated.

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
