Enum CompiledExpr 

pub enum CompiledExpr {
    Not(Box<CompiledExpr>),
    Union(Box<CompiledExpr>, Box<CompiledExpr>),
    Intersection(Box<CompiledExpr>, Box<CompiledExpr>),
    Set(FiltersetLeaf),
}

Variants

Not(Box<CompiledExpr>)

Accepts every test not in the given expression

Union(Box<CompiledExpr>, Box<CompiledExpr>)

Accepts every test in either given expression

Intersection(Box<CompiledExpr>, Box<CompiledExpr>)

Accepts every test in both given expressions

Set(FiltersetLeaf)

Accepts every test in a set

Implementations

impl CompiledExpr

pub const ALL: Self

Returns a value indicating all tests are accepted by this filterset.

pub fn matches_binary( &self, query: &BinaryQuery<'_>, cx: &EvalContext<'_>, ) -> Option<bool>

Returns a value indicating if the given binary is accepted by this filterset.

The value is:

• Some(true) if this binary is definitely accepted by this filterset.
• Some(false) if this binary is definitely not accepted.
• None if this binary might or might not be accepted.

pub fn matches_test(&self, query: &TestQuery<'_>, cx: &EvalContext<'_>) -> bool

Returns true if the given test is accepted by this filterset.

If a group() predicate is encountered, this method panics. Only use this for expressions that are guaranteed group-free (i.e. compiled with any FiltersetKind other than FiltersetKind::Test, or Test expressions where has_group_matchers returns false).

pub fn matches_test_with_groups( &self, query: &TestQuery<'_>, cx: &EvalContext<'_>, groups: &dyn GroupLookup, ) -> bool

Returns true if the given test is accepted by this filterset, resolving group() predicates via the provided lookup.

Use this for FiltersetKind::Test expressions that contain group() predicates.

pub fn has_group_matchers(&self) -> bool

Returns true if this expression contains any group() predicates.

Trait Implementations

impl Clone for CompiledExpr

fn clone(&self) -> CompiledExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompiledExpr

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

Formats the value using the given formatter.

impl PartialEq for CompiledExpr

fn eq(&self, other: &CompiledExpr) -> 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.
