Struct Measured 

pub struct Measured {
    pub rows: Option<usize>,
    pub cols: Option<usize>,
    pub cols_sampled: bool,
    pub size: Option<u64>,
    pub modified: Option<SystemTime>,
    pub stat_only: bool,
    pub columns: Vec<String>,
    pub cost: Cost,
    pub kind: Option<EntryKind>,
    pub holds: Holds,
}

What measuring a dataset yielded; each part absent when unknowable without reading the data.

Fields

rows: Option<usize>

cols: Option<usize>

cols_sampled: bool

Whether cols is a floor rather than a total. See crate::home::discover::Entry.

size: Option<u64>

modified: Option<SystemTime>

When it last changed, from the stat a listing leaves to the rows shown.

stat_only: bool

A stat alone (Reads::StatOnly): its size and mtime, not a measurement, so the row is still measured when it comes on screen.

columns: Vec<String>

Column names, when the format gave them up for free.

cost: Cost

What opening it costs: compression, layout, partitioning, carried to the screen with the row count.

kind: Option<EntryKind>

What the footers said it is when that differs from its filenames (separate tables make a plain directory); usually None. See crate::home::discover::enrich.

holds: Holds

What one listing found, which the row’s label says; only the classify pass counts a local directory.
