Variants

OsError(Error)

Represents a generic OS-level error.

UnsupportedSocketFamily(u32)

Occurs when an unsupported socket family is specified.

FailedToListProcesses(Error)

Used when listing processes fails.

NotAValidSocket

Occurs when an invalid socket is specified.

NotAValidFDType(u32)

Used when an invalid proc_fdtype is specified.

FailedToQueryFileDescriptors(Error)

Used when querying file descriptors fails.

UnsupportedFileDescriptor

Occurs when an unsupported file descriptor is encountered.

FailedToAllocateBuffer

Used when buffer allocation fails.

FailedToGetTcpTable(i32)

Occurs when retrieving the TCP table fails.

FailedToGetUdpTable(i32)

Occurs when retrieving the UDP table fails.

NetLinkError

Represents a NetLink error.

NetLinkPacketError(ErrorMessage)

NetLinkPacketDecodeError(DecodeError)

UnknownProtocol(u8)

Used when an unknown protocol is found.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<DecodeError> for Error

fn from(source: DecodeError) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
