Enum ArgumentKind 

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

Argument type.

Variants

Mandatory

Standard mandatory argument (m).

Optional

Standard optional bracket argument (o).

Star

Star argument (s).

Group

Braced group argument (g or m{}).

Requiredness is enforced by the spec/parser rather than this enum.

Delimited

Single delimited argument (r / d) with matched delimiters.

Fields

open: Delimiter

close: Delimiter

Paired

Paired-candidate argument (r / d with <l,r> pair list) with matched delimiters.

Fields

open: Delimiter

close: Delimiter

Implementations

impl ArgumentKind

pub const fn from_required(required: bool) -> Self

Create an ArgumentKind for standard forms from requiredness.

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 Copy for ArgumentKind

impl Debug for ArgumentKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ArgumentKind

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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.

impl Serialize for ArgumentKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
