Module output 

What a tool prints: a JSON result by default, text on request, and a structured error on stderr whose code is the exit status.

JSON is written here rather than through serde: the values are a handful of scalars, arrays and objects, and a writer this size keeps the tools’ dependencies to their argument parser.

Structs

CliError

A failure: printed as {"error": message, "code": code} on stderr (or <tool>: <message> with --text), and code is the exit status.

Outcome

A successful run’s result.

Enums

Format

JSON or text, from --json/--text (see super::format_args).

Json

A JSON value, with object keys kept in the order they were added so the output reads the way the code builds it.

Constants

EXIT_FAILED

Exit status: the operation failed.

EXIT_UNSUPPORTED

Exit status: the verb exists, and this driver cannot do it — not implemented yet, or the format is read-only.

EXIT_USAGE

Exit status: the command line was wrong (clap’s own choice as well).

Functions

finish

Print a run’s result or failure and turn it into the exit status.

render

What a run’s result or failure prints, and its exit status, without printing it: see super::Response.

text_requested

Whether a raw command line asks for text: the last --text or --json before any -- decides. Format::of reads the order here, and a command line that failed to parse has nothing else to read.
