Enum JsonCmp 

pub enum JsonCmp {
    Eq(Value),
    Ne(Value),
    Gt(Value),
    Lt(Value),
    Ge(Value),
    Le(Value),
    In(Vec<Value>),
    IsNull,
    NotNull,
}

Represents comparison operations for JSON values.

Used with JsonFilter::Extract to compare extracted values against targets.

Variants

Eq(Value)

Equal comparison.

Ne(Value)

Not equal comparison.

Gt(Value)

Greater than comparison.

Lt(Value)

Less than comparison.

Ge(Value)

Greater than or equal comparison.

Le(Value)

Less than or equal comparison.

In(Vec<Value>)

Check if value is in the provided list.

IsNull

Check if value is null or path doesn’t exist.

NotNull

Check if value is not null.

Implementations

impl JsonCmp

pub fn matches(&self, value: Option<Value>) -> bool

Matches the given JSON value against the comparison operation.

In case the provided value is None, and the comparison is IsNull, it returns true. Otherwise, it returns false for None values.

Arguments

• value - An optional JSON value to compare.

Returns

true if the value matches the comparison operation, false otherwise.

Numeric values (every integer variant and Value::Decimal) are compared by magnitude, regardless of their variant, for every operator including Eq, Ne and In. Other values are compared with the Value ordering.

Trait Implementations

impl Eq for JsonCmp

impl PartialEq for JsonCmp

fn eq(&self, other: &Self) -> bool
