Module view 

Front-end helpers shared by the TUI and the GUI: graph history, process table sorting/filtering joined with GPU usage, and small naming helpers.

Nothing here depends on a UI toolkit.

Structs

History

Fixed-size history of samples, newest last.

MetricHistory

Graph histories of one host, updated from each snapshot.

ProcessQuery

How the process table is filtered and sorted.

ProcessRow

One row of the process table: the process plus its GPU usage.

Enums

SortKey

Columns the process table can be sorted by.

Constants

HISTORY_LEN

Number of samples kept for graphs (wider than any realistic terminal in braille dots: 2 samples per cell).

Functions

default_interface

Picks the physical interface with the most traffic so far.

is_virtual_interface

Returns true for container bridges, veth pairs and loopback, which are skipped when choosing and listing interfaces.

process_rows

Processes of snapshot after filtering and sorting, joined with GPU usage.

signal_name

Name of a signal as shown to the user.
