Struct RecordedHints 

#[non_exhaustive]
pub struct RecordedHints {
    pub positive_columns: Vec<String>,
    pub identifier_columns: Vec<String>,
    pub temporal_columns: Vec<String>,
    pub temporal_pair_columns: Vec<String>,
}

The semantic hints a report recorded, by the configuration field that carries each, read from its hint bindings.

Each list is sorted and keeps the repetitions a report recorded. A report written since #1004 records a repeated column once, but one written before it records the column twice and scanned it twice, which moved the timeliness score, so such a report and one listing the column once are not the same configuration.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

positive_columns: Vec<String>

Columns named by positive_columns, sorted.

identifier_columns: Vec<String>

Columns named by identifier_columns, sorted.

temporal_columns: Vec<String>

Columns named by temporal_columns, sorted.

temporal_pair_columns: Vec<String>

Columns named by temporal_pairs, sorted. A report records which columns the pairs named, not which column pairs with which.
