Enum ArgumentKind 

pub enum ArgumentKind {
    Mandatory,
    Optional,
    Star,
    Group,
    Delimited {
        open: Delimiter,
        close: Delimiter,
    },
    Paired {
        open: Delimiter,
        close: Delimiter,
    },
}

Argument slot kind preserved from xparse-aware parsing.

Trait Implementations

impl Clone for ArgumentKind

fn clone(&self) -> ArgumentKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArgumentKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for ArgumentKind

impl PartialEq for ArgumentKind

fn eq(&self, other: &ArgumentKind) -> 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.
