Enum smoltcp::Error

pub enum Error {
    Exhausted,

The error type for the networking stack.

Variants

Exhausted

An operation cannot proceed because a buffer is empty or full.

Illegal

An operation is not permitted in the current state.

Unaddressable

An endpoint or address of a remote host could not be translated to a lower level address. E.g. there was no an Ethernet address corresponding to an IPv4 address in the ARP cache, or a TCP connection attempt was made to an unspecified endpoint.

Truncated

An incoming packet could not be parsed because some of its fields were out of bounds of the received data.

Checksum

An incoming packet had an incorrect checksum and was dropped.

Unrecognized

An incoming packet could not be recognized and was dropped. E.g. an Ethernet packet with an unknown EtherType.

Fragmented

An incoming IP packet has been split into several IP fragments and was dropped, since IP reassembly is not supported.

Malformed

An incoming packet was recognized but was self-contradictory. E.g. a TCP packet with both SYN and FIN flags set.

Dropped

An incoming packet was recognized but contradicted internal state. E.g. a TCP packet addressed to a socket that doesn’t exist.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<Error> for Error

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