    NotFound,
    Moved {
        from: String,
        to: String,
    },
    Conflict,
    BadRequest(String),
    Invalid(Vec<FieldError>),
    Rule(String),
    KeyedRule(Box<KeyedRule>),
    TooManyRequests(Duration),
    Unavailable(String),
    Internal {
        context: String,
        source: Option<Box<dyn Error + Send + Sync>>,

}

Variants

NotFound

Also answered when the principal may not know that the record exists.

Moved

Asked for by a name it had before, such as a slug: a GET is sent on to to.

Implementations

impl Error

pub fn internal( context: impl Into<String>, source: impl Into<Box<dyn Error + Send + Sync>>, ) -> Self

pub fn internal_message(context: impl Into<String>) -> Self

pub fn invalid(field: impl Into<String>, message: impl Into<String>) -> Self

pub fn rule_keyed( key: &'static str, arguments: impl IntoIterator<Item = (&'static str, String)>, message: impl Into<String>, ) -> Self

pub fn into_deserialize_error<E: Error>(self) -> E

Alternate form: the field being read already names the value.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

{:#} prints the message alone, as shown under a field.

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

Formats the value using the given formatter.

impl Error for Error

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<RandomnessUnavailable> for Error

fn from(error: RandomnessUnavailable) -> Self

Converts to this type from the input type.

impl From<RuleText> for Error

fn from(rule: RuleText) -> Self

Converts to this type from the input type.
