What went wrong while validating a value.

Variants

Type

Wrong variant and no coercion applies.

Fields

expected: ValueType

found: ValueType

NotConvertible

Right variant family but the contents cannot be coerced to the target.

Fields

target: ValueType

found: ValueType

Format

A semantic format check failed (host, email, uuid, …).

Fields

expected: &'static str

BelowMin

Numeric value below the inclusive minimum.

Fields

value: String

min: String

AboveMax

Numeric value above the inclusive maximum.

Fields

value: String

max: String

TooShort

String/list/map shorter than the minimum length.

Fields

len: usize

min: usize

TooLong

String/list/map longer than the maximum length.

Fields

len: usize

max: usize

PatternMismatch

String did not match the required pattern.

Fields

pattern: String

Duplicate

A duplicate item was found in a list required to be unique.

Fields

index: usize

MissingKey

A required key was missing from a map.

Fields

key: String

UnknownKey

A key not declared in the schema was present in a map.

Fields

key: String

NotAllowed

A value was not in the allow-list (Enum).

Fields

value: String

Either

Neither alternative of an Either accepted the value.

Fields

first: Box<Error>

second: Box<Error>

Trait Implementations

impl Clone for ErrorKind

fn clone(&self) -> ErrorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl Display for ErrorKind

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

Formats the value using the given formatter.

impl PartialEq for ErrorKind

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