An error during parsing of a descriptor

Variants

NotEnoughData

The amount of data available in the buffer is not enough to hold the descriptor’s declared size.

Fields

tag: u8

descriptor tag value

actual: usize

actual buffer size

expected: usize

expected buffer size

TagTooLongForBuffer

TODO: replace with NotEnoughData

Fields

taglen: usize

actual length in descriptor header

buflen: usize

remaining bytes in buffer (which is seen to be shorter than taglen)

BufferTooShort

The buffer is too short to even hold the two bytes of generic descriptor header data

Fields

buflen: usize

the actual buffer length

UnhandledTagValue(u8)

There is no mapping defined of the given descriptor tag value to a Descriptor value.

Trait Implementations

impl Debug for DescriptorError

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

Formats the value using the given formatter.

impl PartialEq for DescriptorError

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

Tests for self and other values to be equal, and is used by ==.

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

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