Inputs that every engine can provide for centralized profile construction.

Fields

name: String

data_type: DataType

total_count: usize

null_count: usize

unique_count: Option<usize>

sample_values: &'a [String]

text_lengths: Option<TextLengths>

Pre-computed text lengths for engines that track them incrementally. When Some, text stats are built from these instead of re-scanning samples.

boolean_counts: Option<(usize, usize)>

Pre-computed boolean counts (true_count, false_count) for boolean columns.

skip_statistics: bool

When true, skip statistics computation (produce ColumnStats::None).

skip_patterns: bool

When true, skip pattern detection (produce empty patterns vec).

locale: Option<&'a str>

Optional locale for pattern detection (e.g. “IT”, “US”).
