Enum SlotValidator 

pub enum SlotValidator {
    Range {
        min: Option<f64>,
        max: Option<f64>,
    },
    NonEmpty,
    Regex(String),
    OneOf(Vec<String>),
}

A serializable validator applied to a recognized slot value; a value failing it is rejected (the slot stays unfilled until a valid value is recognized).

Variants

Range

Numeric range with optional inclusive bounds (accepts numbers, or numeric strings).

Fields

min: Option<f64>

Inclusive lower bound.

max: Option<f64>

Inclusive upper bound.

NonEmpty

A non-empty (after trim) string.

Regex(String)

A string matching this regex pattern.

OneOf(Vec<String>)

One of a fixed set (case-insensitive for strings).

Implementations

impl SlotValidator

pub fn check(&self, value: &Value) -> bool

Whether value passes this validator.

Trait Implementations

impl Clone for SlotValidator

fn clone(&self) -> SlotValidator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SlotValidator

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SlotValidator

fn deserialize<__D>( __deserializer: __D, ) -> Result<SlotValidator, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SlotValidator

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
