Enum Predicate 

pub enum Predicate {
    Is,
    IsNot,
    Contains,
    DoesNotContain,
    Matches,
    DoesNotMatch,
    LessThan,
    Between,
    Schema,
    NoPredicate,
}

Type representing a condition for assertions.

Predicates are used in the various DSL modules to apply conditions in assertions in a declarative way. A Predicate is used via an Expression.

Variants

Is

Actual should be equals (strictly) to expected.

IsNot

Actual should not be equals (strictly) to expected.

Contains

Actual should contain expected.

DoesNotContain

Actual should not contain expected.

Matches

Actual should match the regex.

DoesNotMatch

Actual should not match the regex.

LessThan

Actual should be less than expected.

Between

Actual should be between the given closed interval [min, max].

Schema

Actual should match the given json schema.

NoPredicate

The absence of predicate for an assertion. Usually used for an unprocessable assertion.

Trait Implementations

impl Clone for Predicate

fn clone(&self) -> Predicate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Predicate

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Predicate

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Predicate

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

Formats the value using the given formatter.

impl PartialEq for Predicate

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Predicate

impl StructuralPartialEq for Predicate
