Errors returned by slug generation or validation.

Variants

EmptyTransliterationPattern

A static transliteration map contains an empty pattern.

EmptyPathSegment

A path segment cannot be empty.

PathSegmentSeparator

A path segment cannot contain / or \.

Fields

character: char

PathSegmentWhitespace

A path segment cannot contain Unicode whitespace.

Fields

character: char

PathSegmentControlCharacter

A path segment cannot contain control characters.

Fields

character: char

PathSegmentDotValue

A path segment cannot be . or ...

UrlPathSegmentReservedCharacter

A URL path segment cannot contain URL delimiter or raw percent characters.

Fields

character: char

FallbackViolatesConfig

A EmptyOutputPolicy::UseFallbackSlug value does not satisfy the configuration that produced the slug it replaces.

Either choose a fallback the configuration could itself have produced, or say the value is exempt with EmptyOutputPolicy::UseVerbatimFallbackSlug. That remedy is named here rather than in the message, because the message is also read by callers who reach this crate through something other than its Rust API and have no such name to type.

Fields

reason: &'static str

Which rule it broke.

AmbiguousReplacementDelimiter

The replacement delimiter is a character this configuration would also keep from the input, so the two could not be told apart.

Choose one the filter removes, such as - or _. Like the fallback above, the remedy lives here and in each surface’s own diagnostics rather than in the message every surface shares.

Fields

delimiter: char

The configured delimiter.

reason: &'static str

Which part of the configuration also claims it.

Trait Implementations

impl Clone for SlugError

fn clone(&self) -> SlugError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SlugError

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

Formats the value using the given formatter.

impl Display for SlugError

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

Formats the value using the given formatter.

impl Eq for SlugError

impl Error for SlugError

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 SlugError

fn eq(&self, other: &SlugError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
