Enum StdError 

pub enum StdError {
    Api(ApiError),
    Io(IoError),
    NoResolvedAddress,
    InvalidSocketAddress,
    InvalidSocketPort,
    MissingDestinationAddress,
    RecursiveDirectoryCreationUnsupported,
    ThreadResultUnavailable,
    NoAvailableCpu,
}

Errors owned by the ArceOS standard-library facade.

Variants

Api(ApiError)

A public ArceOS API operation failed.

Io(IoError)

An ax-io operation failed while implementing a standard-library action.

NoResolvedAddress

Address resolution yielded no usable socket address.

InvalidSocketAddress

A socket address string has invalid syntax.

InvalidSocketPort

A socket port string is not a valid u16 value.

MissingDestinationAddress

A datagram send operation has no destination address.

RecursiveDirectoryCreationUnsupported

Recursive directory creation is not implemented by this facade.

ThreadResultUnavailable

A joined task exited without publishing its return value.

NoAvailableCpu

The runtime reported no available CPU.

Trait Implementations

impl Clone for StdError

fn clone(&self) -> StdError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for StdError

impl Debug for StdError

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

Formats the value using the given formatter.

impl Display for StdError

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

Formats the value using the given formatter.

impl Eq for StdError

impl Error for StdError

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<ApiError> for StdError

fn from(source: ApiError) -> Self

Converts to this type from the input type.

impl From<IoError> for StdError

fn from(source: IoError) -> Self

Converts to this type from the input type.

impl PartialEq for StdError

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

Equality operator ==.

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

Inequality operator !=.
