#[non_exhaustive]
pub enum UrlError {
    Empty,
    TooLong(usize),

Available on crate feature net only.

Error type for URL validation.

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.

Empty

Empty URL

The provided string is empty. URLs must contain at least a scheme.

TooLong(usize)

URL exceeds maximum length of 2048 characters

URLs must not exceed 2048 characters (common browser limit). This variant contains the actual length of the provided URL.

MissingScheme

Missing scheme

URLs must contain a scheme (e.g., http, https, ftp).

InvalidScheme

Invalid scheme

The scheme contains invalid characters. Schemes must start with a letter and contain only letters, digits, +, ., and -.

MissingSchemeSeparator

Missing : after scheme

The scheme must be followed by a colon (:).

MissingAuthority

Missing authority

The URL has // but no authority (host).

InvalidHost

Invalid host

The host part is invalid.

InvalidPort

Invalid port

The port part is invalid.

InvalidChar(char)

Invalid character in URL

The URL contains an invalid character. This variant contains the invalid character.

Trait Implementations

impl Clone for UrlError

fn clone(&self) -> UrlError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UrlError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for UrlError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for UrlError

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

Formats the value using the given formatter.

impl Error for UrlError

Available on crate feature std only.

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 UrlError

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

impl Serialize for UrlError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for UrlError
