Enum TcpError

pub enum TcpError {
    Cancelled,
    TimedOut,
    Incomplete,
    TooBig,
    Failed(Error),
}

The error type for mtcp I/O operations

mtcp I/O operations return a std::io::Result, which will contain an std::io::Error in case of failure. For mtcp-specific errors, the returned std::io::Error contains the suitable variant of mtcp_rs::TcpError as its “inner” error.

Errors from the mio layer are passed through “as-is”; do not expect that an “inner” mtcp_rs::TcpError is always available!

Variants

Cancelled

Indicates that the socket operation was cancelled before completion. Data may have been read or written partially!

TimedOut

Indicates that the socket operation encountered a time-out. Data may have been read or written partially!

Incomplete

Indicates that the socket operation finished (usually because the stream was closed) before all data could be read or written.

TooBig

Indicates that the socket read operation was aborted, because the length of the data would have exceeded the specified limit.

Failed(Error)

Indicates that the socket operation has failed. More detailed information is available via the wrapped io::Error.

Trait Implementations

impl Debug for TcpError

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

Formats the value using the given formatter.

impl Display for TcpError

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

Formats the value using the given formatter.

impl Error for TcpError

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<Error> for TcpError

fn from(value: IoError) -> Self

Converts to this type from the input type.

impl From<TcpError> for Error

fn from(value: TcpError) -> Self

Converts to this type from the input type.
