Struct spirit_daemonize::Opts

#[non_exhaustive]pub struct Opts {
    pub daemonize: bool,
    pub foreground: bool,
}

Command line options fragment.

This adds the -d (--daemonize) and -f (--foreground) flag to command line. These override whatever is written in configuration (if merged together with the configuration).

This can be used to transform the Daemon before daemonization.

The Pipeline here can be used to automatically handle both configuration and command line. See the [crate example][index.html#examples].

Flatten this into the top-level StructOpt structure.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

daemonize: bool

Daemonize ‒ go to background (override the config).

foreground: bool

Stay in foreground (don't go to background even if config says so).

Implementations

impl Opts

pub fn daemonize(&self) -> bool

Returns if daemonization is enabled.

pub fn transform(&self, daemon: Daemon) -> Daemon

Modifies the daemon according to daemonization set.

Trait Implementations

impl Clone for Opts

fn clone(&self) -> Opts

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Opts

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

Formats the value using the given formatter.

impl StructOpt for Opts

fn clap<'a, 'b>() -> App<'a, 'b>

Returns clap::App corresponding to the struct.

fn from_clap(matches: &ArgMatches<'_>) -> Self

Builds the struct from clap::ArgMatches. It's guaranteed to succeed if matches originates from an App generated by StructOpt::clap called on the same type, otherwise it must panic.

fn from_args() -> Self

Builds the struct from the command line arguments (std::env::args_os). Calls clap::Error::exit on failure, printing the error message and aborting the program.

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

Builds the struct from the command line arguments (std::env::args_os). Unlike StructOpt::from_args, returns clap::Error on failure instead of aborting the program, so calling .exit is up to you.

fn from_iter<I>(iter: I) -> Self where
    I: IntoIterator,
    <I as IntoIterator>::Item: Into<OsString>,
    <I as IntoIterator>::Item: Clone, 

Gets the struct from any iterator such as a Vec of your making. Print the error message and quit the program in case of failure.

fn from_iter_safe<I>(iter: I) -> Result<Self, Error> where
    I: IntoIterator,
    <I as IntoIterator>::Item: Into<OsString>,
    <I as IntoIterator>::Item: Clone, 

Gets the struct from any iterator such as a Vec of your making.

impl StructOptInternal for Opts

fn augment_clap<'a, 'b>(app: App<'a, 'b>) -> App<'a, 'b>

fn is_subcommand() -> bool

fn from_subcommand(_sub: (&'b str, Option<&'b ArgMatches<'a>>)) -> Option<Self>
