Trait Implementations

impl Clone for PrimaryExpr

fn clone(&self) -> PrimaryExpr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PrimaryExpr

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

Formats the value using the given formatter.

impl Evaluatable for PrimaryExpr

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

fn is_primitive(&self) -> bool

Returns true if this expression evaluates to a primitive value, without needing to touch the DOM

impl MallocSizeOf for PrimaryExpr

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 PrimaryExpr

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