Enum Constraint 

pub enum Constraint {
    Integer(IntConstraint),
    Double(DoubleConstraint),
    Boolean(BoolConstraint),
    String(StringConstraint),
    Selection(SelectionConstraint),
}

Kind-tagged constraint for dispatch against a Value.

Variants

Integer(IntConstraint)

Constraint over an i64.

Double(DoubleConstraint)

Constraint over an f64.

Boolean(BoolConstraint)

Constraint over a bool.

String(StringConstraint)

Constraint over a String.

Selection(SelectionConstraint)

Constraint over a selection.

Implementations

impl Constraint

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

Test a candidate value against this constraint. Kind-mismatched values always fail.

pub fn canonicalize(self) -> Self

Canonicalise the contained per-kind constraint.

pub fn canonical_bytes(&self) -> Vec<u8>

Canonical byte form. Delegates to the per-kind encoding — the first byte already identifies the kind because each kind uses a disjoint variant-tag range.

pub fn fingerprint(&self) -> Fingerprint

Canonical fingerprint. Delegates to the per-kind fingerprint, which auto-canonicalises.

Trait Implementations

impl Clone for Constraint

fn clone(&self) -> Constraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Constraint

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Constraint

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Constraint

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
