Enum ValidationCode 

pub enum ValidationCode {
    MissingRequiredValue,
    TypeMismatch,
    InvalidValue,
    OutOfRange,
    TooLong,
    TooManyItems,
    UnknownField,
    DuplicateField,
}

A stable, caller-safe explanation for one validation failure.

Variants

MissingRequiredValue

A required value was not provided.

TypeMismatch

A value has the wrong contract type.

InvalidValue

A value has an invalid representation.

OutOfRange

A numeric or temporal value is outside its allowed range.

TooLong

A string or byte value exceeds its allowed length.

TooManyItems

A collection exceeds its allowed item count.

UnknownField

A submitted field is not part of the active contract.

DuplicateField

A submitted record contains a field more than once.

Implementations

impl ValidationCode

pub const fn code(self) -> &'static str

Returns the stable ASCII identifier exposed by every transport.

pub const fn safe_message(self) -> &'static str

Returns a stable public-safe description of the validation failure.

Trait Implementations

impl Clone for ValidationCode

fn clone(&self) -> ValidationCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ValidationCode

impl Debug for ValidationCode

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

Formats the value using the given formatter.

impl Eq for ValidationCode

impl Hash for ValidationCode

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ValidationCode

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