Enum MustDefineRange

pub enum MustDefineRange {
    Inclusive,
    Exclusive,
}

Two related fields must define a range.

This constraint is useful for structs with pairs of fields that define a range such as valid_from and valid_until or min_salary and max_salary.

The validation function can be applied in the RelatedFields context. It is implemented for all types T that implement the PartialOrd trait and Into<Value.

Variants

Inclusive

The first value must be less than or equal to the second value

Exclusive

The first value must be less than the second value

Trait Implementations

impl Clone for MustDefineRange

fn clone(&self) -> MustDefineRange

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MustDefineRange

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

Formats the value using the given formatter.

impl PartialEq for MustDefineRange

fn eq(&self, other: &MustDefineRange) -> 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<T> Validate<MustDefineRange, RelatedFields> for (T, T)

where T: PartialOrd + Into<Value>,

fn validate( self, fields: impl Into<RelatedFields>, constraint: &MustDefineRange, ) -> Validation<MustDefineRange, Self>

Validates this value for being compliant to the specified constraint C in the given context S.
