Struct PathExpression

pub struct PathExpression {
    pub(crate) is_absolute: bool,
    pub(crate) has_implicit_descendant_or_self_step: bool,
    pub(crate) steps: Vec<Expression>,
}

Fields

is_absolute: bool

Whether this is an absolute (as opposed to a relative) path expression.

Absolute paths always start at the starting node, not the context node.

has_implicit_descendant_or_self_step: bool

Whether this expression starts with //. If it does, then an implicit descendant-or-self::node() step will be added.

steps: Vec<Expression>

Implementations

impl PathExpression

fn evaluate<D: Dom>( &self, context: &EvaluationCtx<D>, ) -> Result<Value<D::Node>, Error<D::JsError>>

Trait Implementations

impl Clone for PathExpression

fn clone(&self) -> PathExpression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PathExpression

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

Formats the value using the given formatter.

impl MallocSizeOf for PathExpression

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl PartialEq for PathExpression

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