Enum Reason

pub enum Reason {
    FieldValueInvalid,
    FieldValueForbidden,
    FieldValueRequired,
    FieldValueDuplicate,
}

Reason is a machine-readable value providing more detail about why a field failed the validation.

Variants

FieldValueInvalid

FieldValueInvalid is used to report malformed values (e.g. failed regex match, too long, out of bounds).

FieldValueForbidden

FieldValueForbidden is used to report valid (as per formatting rules) values which would be accepted under some conditions, but which are not permitted by the current conditions (such as security policy).

FieldValueRequired

FieldValueRequired is used to report required values that are not provided (e.g. empty strings, null values, or empty arrays).

FieldValueDuplicate

FieldValueDuplicate is used to report collisions of values that must be unique (e.g. unique IDs).

Trait Implementations

impl Clone for Reason

fn clone(&self) -> Reason

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Reason

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

Formats the value using the given formatter.

impl Default for Reason

fn default() -> Reason

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Reason

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromStr for Reason

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for Reason

fn eq(&self, other: &Reason) -> 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 Reason

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
