Enum ParseError 

pub enum ParseError {
    Unwanted,
    NeedsHint,
    TooSmall,
    StraddledHeader,
    NoRemainingChunks,
    CannotAccept,
    Reject,
    IllegalValue,
}

An error encountered while parsing an individual header.

Variants

Unwanted

Encountered a header which was not allowed by a choice.

NeedsHint

No hint was provided from a previous header, but the current header requires a hint to choose

TooSmall

There are insufficient bytes in the buffer to read the intended header.

StraddledHeader

A header could not be parsed as it was split across several buffers.

NoRemainingChunks

There are no remaining chunks in the Read.

CannotAccept

A parser control attempted to accept an input packet as complete, however the remaining layers are non-optional.

Reject

The packet was explicitly rejected by a parser control block.

IllegalValue

A field in the header had an illegal value for the target datatype.

Implementations

impl ParseError

pub fn as_cstr(&self) -> &'static CStr

Return the name of the error variant as a CStr.

Trait Implementations

impl Clone for ParseError

fn clone(&self) -> ParseError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Error for ParseError

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<Infallible> for ParseError

fn from(_: Infallible) -> Self

Converts to this type from the input type.

impl From<PacketParseError> for ParseError

fn from(value: PacketParseError) -> Self

Converts to this type from the input type.

impl Hash for ParseError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ParseError

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