One row on the home screen.

Fields

path: PathBuf

kind: EntryKind

name: String

Display name — the file or directory name, not the full path.

size: Option<u64>

Size in bytes; for multi-file datasets the sum of files inspected, a floor.

modified: Option<SystemTime>

rows: Option<usize>

Row count, when it can be had without reading data (Parquet footers only).

cols: Option<usize>

Column count, same caveat.

cols_sampled: bool

Whether cols came from a spread of the directory (ends and middle, past the footer budget), so it is a floor, shown as 6+.

columns: Vec<String>

Column names when free to get (a Parquet footer carries them with the row count).

cost: Cost

What opening this costs: where it lives, how it is stored and laid out, from bytes already read.

holds: Holds

What one listing found, for a directory; empty for a file or an unexamined directory.

opens_whole_directory: bool

Whether this row is the door opening the browsed directory. It carries no label: labels count what is directly inside, and this row reads all of it.

format_spec: Option<String>

The format spec that reads this file, by glob or by magic.

table: Option<TableOf>

A table inside a file of tables (SQLite, a NumPy archive): its path is the file’s with the table’s name appended.

measured: bool

Whether a measurement from crate::home::HomeState::enriched is folded into this row, so the passes asking which rows to measure need not look it up.

Implementations

impl Entry

pub fn enter_lists_tables(&self) -> bool

Whether Enter lists the tables inside: a file of several that is not itself a table. A file opening one of its tables, or a spec’s variants file, opens on Enter; → lists them.

pub fn hidden_by_default(&self) -> bool

Whether home hides this row until Ctrl+A: an unreadable file or a database’s internal table.

pub fn label(&self) -> Cow<'static, str>

The short label beside a row’s name, saying what it holds: a looked-into directory’s count (12 parquet, mixed, dir), a lake table’s or hive root’s format, else the kind.

impl Entry

pub fn directory(path: &Path) -> Self

A plain directory row — somewhere to step into, with nothing read from it.

pub fn for_test(path: &Path, name: &str) -> Self

A file entry with a chosen display name, for tests.

Trait Implementations

impl Clone for Entry

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Entry

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
