Struct PortArgs 

pub struct PortArgs {
    pub json: bool,
}

Arguments for trusty-console port.

Why: trusty-installer (tctl) (the orchestrator, issue #1316) discovers the console URL by spawning trusty-console port --json and parsing the {addr,port} envelope (see trusty-installer os_env.rs). The verb must exist and be machine-readable for that discovery to work after the console is de-bundled from the host crates (#1318). What: A single --json flag selecting JSON output (default is a single human-readable port line). Test: test_port_args_json_flag / test_port_args_default below.

Fields

json: bool

Emit a JSON envelope {"addr":"<host>","port":<u16>} instead of a bare port number. Consumed by trusty-installer (tctl) console discovery.

Trait Implementations

impl Args for PortArgs

fn group_id() -> Option<Id>

Report the ArgGroup::id for this set of arguments

fn augment_args<'b>(__clap_app: Command) -> Command

Append to Command so it can instantiate Self via FromArgMatches::from_arg_matches_mut

fn augment_args_for_update<'b>(__clap_app: Command) -> Command

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

impl CommandFactory for PortArgs

fn command<'b>() -> Command

Build a Command that can instantiate Self.

fn command_for_update<'b>() -> Command

Build a Command that can update self.

impl Debug for PortArgs

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

Formats the value using the given formatter.

impl FromArgMatches for PortArgs

fn from_arg_matches(__clap_arg_matches: &ArgMatches) -> Result<Self, Error>

Instantiate Self from ArgMatches, parsing the arguments as needed.

fn from_arg_matches_mut( __clap_arg_matches: &mut ArgMatches, ) -> Result<Self, Error>

Instantiate Self from ArgMatches, parsing the arguments as needed.

fn update_from_arg_matches( &mut self, __clap_arg_matches: &ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.

fn update_from_arg_matches_mut( &mut self, __clap_arg_matches: &mut ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.

impl Parser for PortArgs

fn parse() -> Self

Parse from std::env::args_os(), exit on error.

fn try_parse() -> Result<Self, Error>

Parse from std::env::args_os(), return Err on error.

fn parse_from<I, T>(itr: I) -> Self

where I: IntoIterator<Item = T>, T: Into<OsString> + Clone,
