Struct ValueHintBindingAccumulator 

pub struct ValueHintBindingAccumulator { /* private fields */ }

Accumulates value-driven hint evidence while an engine scans the full data.

The number of configured hints bounds memory use; no cell values are kept.

Implementations

impl ValueHintBindingAccumulator

pub fn new(hints: &SemanticHints) -> Self

pub fn observe(&mut self, column: &str, value: &str)

Observe one cell using the same null and match predicates as the quality calculators and their sample-based binding evidence.

pub fn bindings<'a>( &self, column_names: impl IntoIterator<Item = &'a str>, ) -> Vec<SemanticHintBinding>

Return exact evidence for hints whose columns exist in the source. Unknown names remain the schema validator’s responsibility.

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