Struct RecordSet 

pub struct RecordSet {
    pub source: String,
    pub format: String,
    pub columns: Vec<Column>,
}

A normalized corpus: named columns of equal length, plus provenance about where it came from. This is the universal input to every detector.

Fields

source: String

Logical source identifier (path, URL, or "-" for stdin).

format: String

The format the normalizer recognized (e.g. "csv", "ndjson").

columns: Vec<Column>

Implementations

impl RecordSet

pub fn new( source: impl Into<String>, format: impl Into<String>, columns: Vec<Column>, ) -> Self

Creates a record set, panicking only via debug-assert if columns are ragged. Construction is the normalizer’s responsibility; detectors may rely on rectangularity.

pub fn rows(&self) -> usize

Number of rows (length of the first column, or 0 if columnless).

pub fn width(&self) -> usize

pub fn column(&self, name: &str) -> Option<&Column>

pub fn select(&self, names: &[String]) -> RecordSet

A copy keeping only the columns named in names, in their original column order (not the order given). Names with no matching column are silently skipped — callers that must reject an unknown name should validate with Self::column first. Provenance is preserved.

This is the column-scoping primitive behind scan --columns: it lets a caller focus detection on a handful of meaningful columns in a wide corpus (e.g. journald’s dozens of identifier/counter fields).

pub fn without(&self, names: &[String]) -> RecordSet

A copy dropping the columns named in names, preserving the order and provenance of the rest. The complement of Self::select, behind scan --exclude.

Trait Implementations
