Struct ErrorCode

pub struct ErrorCode { /* private fields */ }

Describes error code of particular category.

Implementations

impl ErrorCode

pub const fn new(code: i32, category: &'static Category) -> ErrorCode

Initializes error code with provided category

pub fn new_posix(code: i32) -> ErrorCode

Creates new POSIX error code.

pub fn new_system(code: i32) -> ErrorCode

Creates new System error code.

pub fn last_posix() -> ErrorCode

Gets last POSIX error

pub fn last_system() -> ErrorCode

Gets last System error

pub const fn raw_code(&self) -> i32

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<(), Error>

Formats the value using the given formatter.

impl Display for ErrorCode

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

Formats the value using the given formatter.

impl Hash for ErrorCode

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

where H: Hasher,

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 NngError for ErrorCode

fn is_cancelled(&self) -> bool

Returns whether error code indicates cancellation of future.

fn is_timed_out(&self) -> bool

Returns whether error code indicates operation timed out.

fn is_conn_aborted(&self) -> bool

Returns whether error code indicates aborted connection.

fn is_conn_reset(&self) -> bool

Returns whether error code indicates connection has been reset.

fn is_conn_refused(&self) -> bool

Returns whether error code indicates connection has been refused.

fn is_peer_auth(&self) -> bool

Returns whether error code indicates problem with peer’s authentication

fn is_crypto(&self) -> bool

Returns whether error code indicates problem using crypto

impl PartialEq for ErrorCode

fn eq(&self, other: &ErrorCode) -> 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.
