Enum PatternError

#[non_exhaustive]
pub enum PatternError {
    FieldLengthInvalid(FieldSymbol),
    UnknownSubstitution(char),
    InvalidSymbol(char),
    UnclosedLiteral,
    UnclosedPlaceholder,
    UnsupportedPluralPivot,
}

A low-level pattern parsing error.

These strings follow the recommendations for the serde::de::Unexpected::Other type. https://docs.serde.rs/serde/de/enum.Unexpected.html#variant.Other

Serde will generate an error such as: “invalid value: unclosed literal in pattern, expected a valid UTS 35 pattern string at line 1 column 12”

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.

FieldLengthInvalid(FieldSymbol)

UnknownSubstitution(char)

InvalidSymbol(char)

UnclosedLiteral

UnclosedPlaceholder

UnsupportedPluralPivot

Trait Implementations

impl Clone for PatternError

fn clone(&self) -> PatternError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PatternError

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

Formats the value using the given formatter.

impl Display for PatternError

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

Formats the value using the given formatter.

impl Error for PatternError

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<Error> for PatternError

fn from(input: Error) -> PatternError

Converts to this type from the input type.

impl PartialEq for PatternError

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