Enum app::OptTypo

pub enum OptTypo {
    Single,
    Ignored,
    Covered,
    Multiple(Option<usize>),
}

OptionType

You should ignore OptTypo if the Opt is a flag(trait OptValueParse: is_bool).

Variants

Single

App will exit if the Opt occurs for the second time.

Ignored

App will ignore all values of the Opt except the first time.

Covered

Default: App will overwrite the previous value with a later value.

Multiple(Option<usize>)

App will accumulate all values of the Opt if the Opt's value is Vec<T> or &mut [T], otherwise it equal to Covered(default).

The value is the length set for Vec<T> or &[T], default is None or the length of &mut [T].

Methods
