Struct ComparisonExpr

pub struct ComparisonExpr { /* private fields */ }

Comparison based on two singular values and a comparison operator.

Examples

let lhs = Comparable::from(Literal::from("abc"));
let rhs = Comparable::RelativeSingularQuery(
    SingularJsonPathQuery::from_iter(vec![])
);
let comparison = ComparisonExpr::from_parts(
    lhs.clone(),
    ComparisonOp::EqualTo,
    rhs.clone());

assert_eq!(&lhs, comparison.lhs());
assert_eq!(ComparisonOp::EqualTo, comparison.op());
assert_eq!(&rhs, comparison.rhs());

Implementations

impl ComparisonExpr

pub fn lhs(&self) -> &Comparable

Get the comparable left-hand side of the comparison operation.

pub fn op(&self) -> ComparisonOp

Get the comparison operator.

pub fn rhs(&self) -> &Comparable

Get the comparable right-hand side of the comparison operation.

pub fn from_parts(lhs: Comparable, op: ComparisonOp, rhs: Comparable) -> Self

Construct a ComparisonExpr from its constituent parts.

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for ComparisonExpr

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl Clone for ComparisonExpr

fn clone(&self) -> ComparisonExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ComparisonExpr

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ComparisonExpr

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ComparisonExpr

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

Formats the value using the given formatter.

impl Hash for ComparisonExpr

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ComparisonExpr

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
