Enum PredicateError 

pub enum PredicateError {
    MissingField {
        suffix: String,
        field: String,
    },
    TypeMismatch {
        suffix: String,
        field: String,
        expected: String,
    },
    NotAnObject {
        suffix: String,
    },
    SchemaParse {
        suffix: String,
        detail: String,
    },
}

A payload that does not conform to its predicate schema.

Variants

MissingField

A required field was absent from the payload.

Fields

suffix: String

field: String

TypeMismatch

A present field did not match its declared type.

Fields

suffix: String

field: String

expected: String

NotAnObject

The payload was not a JSON object (registered predicates require one).

Fields

suffix: String

SchemaParse

The embedded schema itself failed to parse (a build-time bug).

Fields

suffix: String

detail: String

Trait Implementations

impl Clone for PredicateError

fn clone(&self) -> PredicateError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PredicateError

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

Formats the value using the given formatter.

impl Display for PredicateError

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

Formats the value using the given formatter.

impl Eq for PredicateError

impl Error for PredicateError

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 PredicateError

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