Struct OptGroup

pub(crate) struct OptGroup {
    pub(crate) short_name: String,
    pub(crate) long_name: String,
    pub(crate) hint: String,
    pub(crate) desc: String,
    pub(crate) hasarg: HasArg,
    pub(crate) occur: Occur,
}

One group of options, e.g., both -h and --help, along with their shared description and properties.

Fields

short_name: String

Short name of the option, e.g. h for a -h option

long_name: String

Long name of the option, e.g. help for a --help option

hint: String

desc: String

Description for usage help text

hasarg: HasArg

Whether option has an argument

occur: Occur

How often it can occur

Implementations

impl OptGroup

pub(crate) fn long_to_short(&self) -> Opt

Translate OptGroup into Opt. (Both short and long names correspond to different Opts).

Trait Implementations

impl Clone for OptGroup

fn clone(&self) -> OptGroup

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Eq for OptGroup

#[doc(hidden)] fn assert_receiver_is_total_eq(&self)

impl PartialEq for OptGroup

fn eq(&self, other: &OptGroup) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
