Parsing a mention failed due to invalid syntax.

Variants

IdNotU64

ID portion of the mention isn't a u64.

Fields of IdNotU64

found: &'a str

String that could not be parsed into a u64.

source: ParseIntError

Reason for the error.

LeadingArrow

Leading arrow (<) is not present.

Fields of LeadingArrow

found: Option<char>

Character that was instead found where the leading arrow should be.

PartMissing

One or more parts of the mention are missing.

For example, an emoji mention - <:name:id> - has two parts: the name and the id, separated by the sigil (:). If the second sigil denoting the second part can't be found, then it is missing.

Fields of PartMissing

expected: usize

Number of parts that are expected.

found: usize

Number of parts that have been found.

Sigil

Mention's sigil is not present.

Users, for example, have the sigil @.

Fields of Sigil

expected: &'a [&'a str]

Possible sigils that were expected for the mention type.

found: Option<char>

Character that was instead found where the sigil should be.

TrailingArrow

Trailing arrow (>) is not present.

Fields of TrailingArrow

found: Option<char>

Character that was instead found where the trailing arrow should be.

Trait Implementations

impl<'a> Clone for ParseMentionError<'a>

pub fn clone(&self) -> ParseMentionError<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for ParseMentionError<'a>

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

Formats the value using the given formatter.

impl Display for ParseMentionError<'_>

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

impl<'a> Eq for ParseMentionError<'a>

impl Error for ParseMentionError<'_>

pub fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl<'a> PartialEq<ParseMentionError<'a>> for ParseMentionError<'a>
