Errors produced by the IMAP response parser.

Variants

Incomplete

Input ended before a complete response could be parsed. The caller should accumulate more bytes and retry.

InvalidChar(usize)

A byte that is invalid at the current grammar position was found. The value is the byte offset into the input where it occurred.

ExpectedLiteral

An expected literal token was not present at the given offset.

Fields

expected: String

The literal token the parser expected to find.

offset: usize

Byte offset into the input where the literal was expected.

UnexpectedEof

Input ended unexpectedly in the middle of a token.

InvalidNumber

A numeric field could not be parsed as a valid integer.

LiteralTooLarge

A literal whose declared length exceeds the parser’s hard cap. Used as an explicit DoS guard against hostile servers.

Fields

got: usize

Literal length declared by the server, in octets.

max: usize

Maximum literal length the parser accepts, in octets.

Malformed(&'static str)

Well-formed bytes that nonetheless violate the response grammar. The value is a human-readable description of the violation.

Other(&'static str)

A parsing error that does not fit any of the more specific variants.

Trait Implementations

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

Formats the value using the given formatter.

impl Eq for ParseError

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.
