Structured error returned by try_from_* parsing APIs.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

BufferTooShort

The input buffer was shorter than the protocol minimum.

Fields

context: &'static str

Human-readable parse context.

minimum: usize

Minimum required number of bytes.

actual: usize

Actual number of bytes available.

InvalidLength

A length-like field contained an invalid value.

Fields

context: &'static str

Human-readable parse context.

value: usize

Parsed value that failed validation.

Malformed

The packet contains a malformed header field.

Fields

context: &'static str

Human-readable parse context.

Truncated

The packet payload was truncated relative to its header lengths.

Fields

context: &'static str

Human-readable parse context.

expected: usize

Expected number of bytes.

actual: usize

Actual number of bytes available.

CompressionLoop

Parsing failed because a compression loop or excessive indirection was detected.

Fields

context: &'static str

Human-readable parse context.

InvalidCompression

Parsing failed because an unsupported or invalid pointer/compression form was encountered.

Fields

context: &'static str

Human-readable parse context.

InvalidUtf8

A UTF-8 conversion failed while parsing text-like data.

Fields

context: &'static str

Human-readable parse context.

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 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.
