## ArgPredicate

# Enum 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?
