Error type for KCP protocol operations.

Each variant maps to a specific failure condition when interacting with the underlying KCP C library through the safe Kcp wrapper.

Variants

CreateFailed

Failed to create a KCP instance (e.g., ikcp_create returned null).

SendFailed(i32)

Failed to send data through KCP. The inner value is the C error code.

RecvWouldBlock

No data is available to receive right now. This is not a fatal error; the caller should retry after feeding more input data and calling update().

RecvBufferTooSmall

The provided receive buffer is too small for the next message.

Fields

need: usize

The size of the next available message.

got: usize

The size of the buffer that was provided.

RecvFailed(i32)

A generic receive failure with the C error code.

InputFailed(i32)

Failed to feed input data to the KCP engine (e.g., corrupted packet).

SetMtuFailed

Failed to set the MTU to the specified value.

Fields

mtu: u32

The MTU value that was attempted.

code: i32

The C error code returned.

InvalidConfig(String)

An invalid configuration parameter was provided.

ConvMismatch

The conversation ID in the received packet does not match the expected one.

Fields

expected: u32

The expected conversation ID.

got: u32

The conversation ID found in the packet.

OutputError(Error)

An I/O error occurred in the output callback.

Trait Implementations

impl Debug for KcpError

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

Formats the value using the given formatter.

impl Display for KcpError

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

Formats the value using the given formatter.

impl Error for KcpError

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 KcpError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<KcpError> for KcpTokioError

fn from(source: KcpError) -> Self

Converts to this type from the input type.
