Enum SingularArgSyntax 

pub enum SingularArgSyntax {
    RequiredValue(RequiredValueSyntax, ArgSepSyntax),
    RequiredRef(RequiredRefSyntax, ArgSepSyntax),
    OptionalValue(OptionalValueSyntax, ArgSepSyntax),
    AnyValue(AnyValueSyntax, ArgSepSyntax),
}

Syntax specification for a non-repeated argument.

Every item in this enum is composed of a struct that provides the details on the parameter and a struct that provides the details on how this parameter is separated from the next.

Variants

RequiredValue(RequiredValueSyntax, ArgSepSyntax)

A required scalar value with the syntax details and the separator that follows.

RequiredRef(RequiredRefSyntax, ArgSepSyntax)

A required reference with the syntax details and the separator that follows.

OptionalValue(OptionalValueSyntax, ArgSepSyntax)

An optional scalar value with the syntax details and the separator that follows.

AnyValue(AnyValueSyntax, ArgSepSyntax)

A required scalar value of any type with the syntax details and the separator that follows.

Trait Implementations

impl Clone for SingularArgSyntax

fn clone(&self) -> SingularArgSyntax

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SingularArgSyntax

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

Formats the value using the given formatter.

impl PartialEq for SingularArgSyntax

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