Struct error_code::ErrorCode

pub struct ErrorCode { /* private fields */ }

Describes error code of particular category.

Implementations

impl ErrorCode

pub const fn new(code: c_int, category: &'static Category) -> Self

Initializes error code with provided category

pub fn new_posix(code: c_int) -> Self

Creates new POSIX error code.

pub fn new_system(code: c_int) -> Self

Creates new System error code.

pub fn last_posix() -> Self

Gets last POSIX error

pub fn last_system() -> Self

Gets last System error

pub const fn raw_code(&self) -> c_int

Gets raw error code.

pub const fn category(&self) -> &'static Category

Gets reference to underlying Category.

pub fn is_would_block(&self) -> bool

Returns true if underlying error indicates operation can or should be re-tried at later date.

Trait Implementations

impl Clone for ErrorCode

fn clone(&self) -> ErrorCode

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ErrorCode

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ErrorCode

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ErrorCode

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for ErrorCode

fn from(err: Error) -> Self

Converts to this type from the input type.

impl Hash for ErrorCode

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ErrorCode

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
