Enum wasi_common::ErrorKind

#[non_exhaustive]
pub enum ErrorKind {
    TooBig,
    Badf,
    Ilseq,
    Io,
    Nametoolong,
    Notdir,
    Notsup,
    Overflow,
    Range,
    Spipe,
    Perm,
}

Internal error type for the wasi-common crate.

This Contains variants of the WASI $errno type that are used internally by the crate, and which aren’t one-to-one with a std::io::ErrorKind error.

When the Rust io_error_more feature is stabilized, that will enable us to replace several more of these codes with std::io::ErrorKind codes.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

TooBig

Errno::TooBig: Argument list too long

Badf

Errno::Badf: Bad file descriptor

Ilseq

Errno::Ilseq: Illegal byte sequence

Io

Errno::Io: I/O error

Nametoolong

Errno::Nametoolong: Filename too long

Notdir

Errno::Notdir: Not a directory or a symbolic link to a directory.

Notsup

Errno::Notsup: Not supported, or operation not supported on socket.

Overflow

Errno::Overflow: Value too large to be stored in data type.

Range

Errno::Range: Result too large

Spipe

Errno::Spipe: Invalid seek

Perm

Errno::Perm: Permission denied

Trait Implementations

impl Clone for ErrorKind

fn clone(&self) -> ErrorKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl Display for ErrorKind

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

Formats the value using the given formatter.

impl Error for ErrorKind

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<ErrorKind> for Errno

fn from(e: ErrorKind) -> Errno

Converts to this type from the input type.

impl PartialEq<ErrorKind> for ErrorKind

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