Struct Printer 

pub struct Printer { /* private fields */ }

Main printer for CLI output

Implementations

impl Printer

pub fn new(format: OutputFormat, verbose: bool) -> Self

Creates a new printer with the specified format and verbosity.

pub fn from_flags(json: bool, verbose: bool) -> Self

Create a printer from common CLI flags.

pub fn success(&self, message: &str)

Print a success message (human only — use print_empty_result for JSON-safe success)

pub fn print_empty_result(&self, action: &str, message: &str)

Print a “nothing found” success result with JSON support.

In human mode, prints a green success message. In JSON mode, outputs structured JSON so scripts/LLMs always get parseable output.

pub fn error(&self, message: &str)

Print an error message

pub fn warning(&self, message: &str)

Print a warning message

pub fn print_processes_as( &self, action: &str, processes: &[Process], context: Option<&str>, )

Print a list of processes with action name and optional context.

The action parameter sets the JSON action field (e.g. “list”, “by”, “stuck”).

pub fn print_processes_with_context( &self, processes: &[Process], context: Option<&str>, )

Print a list of processes with optional context (e.g., “in /path/to/dir”). Uses “list” as the JSON action name.

pub fn print_processes(&self, processes: &[Process])

Print a list of processes. Uses “list” as the JSON action name.

pub fn print_ports(&self, ports: &[PortInfo])

Print port information

pub fn print_port_info(&self, port_info: &PortInfo)

Print a single port info (for proc on :port)

pub fn print_json<T: Serialize>(&self, data: &T)

Print JSON output for any serializable type

pub fn print_action_result( &self, action: &str, succeeded: &[Process], failed: &[(Process, String)], )

Print action result (generalized for kill/stop/unstick).

The action parameter should be a lowercase verb (e.g. “kill”, “stop”, “freeze”). It is used as-is in JSON output and capitalized for human display.

pub fn print_kill_result( &self, killed: &[Process], failed: &[(Process, String)], )

Print kill result (delegates to print_action_result)

pub fn print_dry_run(&self, verb: &str, processes: &[Process])

Print dry-run summary and return early.

Used by destructive commands (kill, stop, freeze, thaw) for consistent dry-run output.

pub fn ask_confirm( &self, action: &str, processes: &[Process], yes: bool, ) -> Result<bool>

Show confirmation prompt and return whether the user confirmed.

Returns Ok(true) if confirmed or skipped (–yes / –json). Returns Ok(false) if the user declined (prints “Cancelled”).

pub fn print_confirmation(&self, action: &str, processes: &[Process])

Print a confirmation prompt showing processes about to be acted on

Trait Implementations

impl Default for Printer

fn default() -> Self

Returns the “default value” for a type.
