Struct EffectTrace 

pub struct EffectTrace { /* private fields */ }

An effect trace that collects effects during parsing.

Effect traces are composable and can be filtered or transformed.

Implementations

impl EffectTrace

pub fn new() -> Self

Create a new empty effect trace.

pub fn record(&mut self, effect: ParserEffect)

Record an effect in the trace.

If the effect is terminal (FailClosed), subsequent effects are still recorded but the trace is marked as terminated.

pub fn is_terminated(&self) -> bool

Returns true if the trace contains any terminal effects.

pub fn is_empty(&self) -> bool

Returns true if the trace has no effects.

pub fn len(&self) -> usize

Returns the number of effects in the trace.

pub fn effects(&self) -> &[ParserEffect]

Returns a slice of all effects.

pub fn terminal(&self) -> Option<&ParserEffect>

Returns the terminal effect, if any.

pub fn filter_kind(&self, kind: ParserEffectKind) -> Vec<&ParserEffect>

Filter effects by kind.

pub fn count_kind(&self, kind: ParserEffectKind) -> usize

Count effects by kind.

pub fn warnings(&self) -> Vec<&ParserEffect>

Returns all warning effects.

pub fn merge(&mut self, other: EffectTrace)

Merge another trace into this one.

pub fn summary(&self) -> EffectTraceSummary

Convert to a summary for logging.

Trait Implementations

impl Clone for EffectTrace

fn clone(&self) -> EffectTrace

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EffectTrace

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

Formats the value using the given formatter.

impl Default for EffectTrace

fn default() -> EffectTrace

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for EffectTrace

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for EffectTrace

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

impl Serialize for EffectTrace

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
