Trait Implementations

impl Args for Opts

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

Append to App so it can instantiate Self.

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

Append to App so it can update self.

impl FromArgMatches for Opts

fn from_arg_matches(__clap_arg_matches: &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.

impl IntoApp for Opts

fn into_app<'b>() -> App<'b>

Build an App that can instantiate Self.

fn into_app_for_update<'b>() -> App<'b>

Build an App that can update self.

impl Parser for Opts

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, 

Parse from iterator, exit on error

fn try_parse_from<I, T>(itr: I) -> Result<Self, Error> where
    I: IntoIterator<Item = T>,
    T: Into<OsString> + Clone, 

Parse from iterator, return Err on error.

fn update_from<I, T>(&mut self, itr: I) where
    I: IntoIterator<Item = T>,
    T: Into<OsString> + Clone, 

Update from iterator, exit on error

fn try_update_from<I, T>(&mut self, itr: I) -> Result<(), Error> where
    I: IntoIterator<Item = T>,
    T: Into<OsString> + Clone, 

Update from iterator, return Err on error.
