Fields

selector: Option<String>

Selector expression (e.g., foo.bar, items[0].name, [*].id)

input: InputFormat

Input format override

output: OutputFormat

Output format override (default: auto-match input)

file: Option<String>

Read from file instead of stdin

json: bool

Output result as JSON

raw: bool

Output without trailing newline

first: bool

Only output first result

lines: bool

Output array elements one per line

default: Option<String>

Default value if selector doesn’t match

quiet: bool

Suppress error messages

exists: bool

Check if selector matches (exit code only: 0=found, 1=not found)

count: bool

Output count of matches

stream: bool

Stream mode: process JSONL input line-by-line

Trait Implementations

impl Args for Cli

fn group_id() -> Option<Id>

Report the ArgGroup::id for this set of arguments

Append to Command so it can instantiate self via FromArgMatches::update_from_arg_matches_mut

impl CommandFactory for Cli

fn command<'b>() -> Command

Build a Command that can instantiate Self.

fn command_for_update<'b>() -> Command

impl Debug for Cli

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

Formats the value using the given formatter.
