Fields

version: u8

topics: BTreeMap<u16, Topic>

Each topic and instance with data, by message id.

names: Vec<(String, u16)>

The table name of each topic with data, in the listing’s order.

info: Vec<(String, String)>

parameters: Vec<(String, &'static str, f64, Option<u64>)>

Name, type, value, and the time it was set past the header (None for the initial value).

logged: Vec<(u64, &'static str, Option<u16>, String)>

Timestamp, level, tag, text.

logged_left_out: usize

dropouts: usize

dropout_ms: u64

skipped: usize

Bytes passed over as damaged, and how many stretches.

damaged: usize

short: usize

Data messages too short for their topic’s fields, left out.

unsubscribed: usize

Data messages with an id no subscription gave.

past_limit: usize

Records past limits.indexed_records, left out.

unread: Vec<(String, String)>

Why a topic’s fields could not be read, by topic.

cut_short: bool

A data section that runs past what the file holds: written while logging.

Trait Implementations

impl Debug for Index

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

Formats the value using the given formatter.

impl Default for Index

fn default() -> Self

Returns the “default value” for a type.

impl Log for Index

const EMPTY: &'static str = " The log has no data messages."

Said after “the file holds no tables.” of a log with none.

fn index(data: &[u8]) -> Result<Self, String>

fn tables(&self) -> Vec<Table>

Its tables, for the home screen and --table.

fn detail(&self) -> Detail

What the Info panel’s tab of it says.

fn notes(&self) -> Vec<String>

What the Notes tab says of the pass.

fn table( &self, bytes: Arc<Bytes>, name: &str, opened: &mut Opened, ) -> Result<LazyFrame, String>

The table name, one of Self::tables, read from bytes, filling what of opened it knows (its window, units).
