Enum clap::builder::ArgPredicate

source · [−]

pub enum ArgPredicate {
    IsPresent,
    Equals(OsStr),
}

Expand description

Operations to perform on argument values

These do not apply to ValueSource::DefaultValue

Variants

`IsPresent`

Is the argument present?

`Equals(OsStr)`

Does the argument match the specified value?
