Struct Expression

pub struct Expression<T> {
    pub predicate: Predicate,
    pub value: T,
}

Represents an expected value associated to a Predicate to run against another value.

An expression is used to build assertions. It is composed of a Predicate and an expected value that will be used to create expressive assertion functions like this one : status(is_between(200, 204)). In this example we assert that the actual StatusCode is Between a closed Range.

Fields

predicate: Predicate

The Predicate to apply in an assertion.

value: T

The expected value as part of the Predicate.

Trait Implementations

impl<T: Debug> Debug for Expression<T>

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

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for Expression<T>

where T: Deserialize<'de>,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: PartialEq> PartialEq for Expression<T>

fn eq(&self, other: &Expression<T>) -> 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.
