Enum EffectOp

pub enum EffectOp {

}

Effect operation in the IR effect stream.

Effects are executed sequentially after a successful match. They manipulate a value stack to construct structured output.

Variants

CaptureNode

Store matched node as current value. Only valid on transitions with Node/Anonymous/Wildcard matcher.

ClearCurrent

Clear current value (set to None). Used on skip paths for optional captures.

StartArray

Push empty array onto stack.

PushElement

Move current value into top array.

EndArray

Pop array from stack into current.

StartObject

Push empty object onto stack.

EndObject

Pop object from stack into current.

Field(DataFieldId)

Move current value into top object at field.

StartVariant(VariantTagId)

Push variant container with tag onto stack.

EndVariant

Pop variant, wrap current, set as current.

ToString

Replace current Node with its source text.

Trait Implementations

impl Clone for EffectOp

fn clone(&self) -> EffectOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EffectOp

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

Formats the value using the given formatter.

impl PartialEq for EffectOp

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