Module formatter 

Output formatting for speed test results.

This module is organized into submodules:

• ratings — Rating helper functions (ping, speed, connection, bufferbloat)
• sections — Output section formatters (latency, download, upload, etc.)
• stability — Speed stability analysis and latency percentiles
• estimates — Usage check targets and download time estimates

Modules

dashboard

Dashboard output formatting — rich single-screen summary with gauges and sparklines.

estimates

Usage check targets and real-world download time estimates.

ratings

Rating helper functions for speed test results.

scenarios

Grouped, category-based internet usage scenario display.

sections

Output section formatters for detailed test results.

stability

Speed stability analysis and latency percentiles.

Structs

FormatterFactory

Factory for creating formatter instances.

SkipState

Which test phases were skipped by the user (e.g. --no-download).

Enums

OutputFormat

Output format selection — Strategy pattern. Add new variants here to extend output formats (OCP).

Traits

Formatter

Trait for output formatting strategies.

Functions

format_compact

Compact mode — key metrics with ratings and brief summary. Middle ground between simple (too minimal) and detailed (too verbose).

format_csv

Output test results as CSV to stdout.

format_detailed

Detailed mode — clean key/value pairs.

format_json

Output test results as JSON to stdout.

format_jsonl

JSONL mode — one JSON object per line, ideal for logging/parsing.

format_minimal

Minimal mode — ultra-compact: just “B+ 150.5↓ 25.3↑ 12ms”

format_simple

Simple mode — single line.

format_verbose_sections

Format additional verbose output sections: stability, latency percentiles, and historical comparison. Only used in detailed (verbose) mode.
