Struct LowerAttributesReport 

pub struct LowerAttributesReport {
    pub attributes: HashMap<AttributeSet, AttributeStat>,
    pub eliminated_empty_segments: usize,
}

Statistics accumulated across every LowerAttributes invocation in one transform run.

The engine can run LowerAttributes before and after Rewrite. This report intentionally aggregates both invocations instead of splitting pre/post counters.

Fields

attributes: HashMap<AttributeSet, AttributeStat>

Per-attribute counters for consumed inputs and emitted canonical forms.

eliminated_empty_segments: usize

Trailing changepoints whose segment ended up empty (e.g. {x \bf} or \sqrt{\bf}).

Trait Implementations

impl Clone for LowerAttributesReport

fn clone(&self) -> LowerAttributesReport

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LowerAttributesReport

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

Formats the value using the given formatter.

impl Default for LowerAttributesReport

fn default() -> LowerAttributesReport

Returns the “default value” for a type.

impl Eq for LowerAttributesReport

impl PartialEq for LowerAttributesReport

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