Expand description

Reasons a decode call may fail.

Variants§

§

Incomplete

Buffer ended before a complete packet could be read.

Fields

§need: usize

Number of bytes the decoder needed to be present.

§have: usize

Number of bytes actually available.

§

BadToken

Start token at offset 0 did not match PACKET_TOKEN.

Fields

§expected: u16

The constant token expected.

§got: u16

The token actually decoded.

§

HeaderChecksum

Recomputed Fletcher-16 over the header bytes did not match the stored value.

Fields

§stored: u16

Checksum stored in the packet.

§computed: u16

Checksum computed from the header bytes.

§

PayloadChecksum

Recomputed Fletcher-16 over the body bytes did not match the stored value.

Fields

§stored: u16

Checksum stored after the payload.

§computed: u16

Checksum computed from the body bytes.

impl PartialEq for DecodeError

Source§

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

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
