Formatters for logging `tracing` events. -//! -//! This module provides several formatter implementations, as well as utilities -//! for implementing custom formatters. -//! -//! # Formatters -//! This module provides a number of formatter implementations: -//! -//! * [`Full`]: The default formatter. This emits human-readable, -//! single-line logs for each event that occurs, with the current span context -//! displayed before the formatted representation of the event. See -//! [here](Full#example-output) for sample output. -//! -//! * [`Compact`]: A variant of the default formatter, optimized for -//! short line lengths. Fields from the current span context are appended to -//! the fields of the formatted event, and span names are not shown; the -//! verbosity level is abbreviated to a single character. See -//! [here](Compact#example-output) for sample output. -//! -//! * [`Pretty`]: Emits excessively pretty, multi-line logs, optimized -//! for human readability. This is primarily intended to be used in local -//! development and debugging, or for command-line applications, where -//! automated analysis and compact storage of logs is less of a priority than -//! readability and visual appeal. See [here](Pretty#example-output) -//! for sample output. -//! -//! * [`Json`]: Outputs newline-delimited JSON logs. This is intended -//! for production use with systems where structured logs are consumed as JSON -//! by analysis and viewing tools. The JSON output is not optimized for human -//! readability.
