Implementations

impl Errno

pub fn name(&self) -> &'static str

pub fn message(&self) -> &'static str

Trait Implementations

impl Clone for Errno

fn clone(&self) -> Errno

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Errno

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

Formats the value using the given formatter.

impl Display for Errno

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

Formats the value using the given formatter.

impl Error for Errno

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

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, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

impl From<WasiThreadError> for Errno

fn from(a: WasiThreadError) -> Errno

Converts to this type from the input type.

impl FromToNativeWasmType for Errno

type Native = i32

Native Wasm type.

fn to_native(self) -> <Errno as FromToNativeWasmType>::Native

Convert self to Self::Native.

fn from_native(n: <Errno as FromToNativeWasmType>::Native) -> Errno

Convert a value of kind Self::Native to Self.

fn is_from_store(&self, _store: &impl AsStoreRef) -> bool

Returns whether the given value is from the given store.

impl PartialEq<Errno> for Errno

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl ValueType for Errno

fn zero_padding_bytes(&self, _bytes: &mut [MaybeUninit<u8>])

This method is passed a byte slice which contains the byte representation of self. It must zero out any bytes which are uninitialized (e.g. padding bytes).

impl Copy for Errno

impl Eq for Errno

impl StructuralEq for Errno

impl StructuralPartialEq for Errno
