Nullptr

A null pointer or null member pointer provided for a non-type template parameter.

Pack

A parameter pack.

Template

A name for a template provided for a template template parameter.

TemplateExpansion

Trait Implementations

impl<'tu> Clone for TemplateArgument<'tu>

fn clone(&self) -> TemplateArgument<'tu>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'tu> Debug for TemplateArgument<'tu>

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

Formats the value using the given formatter.

impl<'tu> PartialEq for TemplateArgument<'tu>

fn eq(&self, other: &TemplateArgument<'tu>) -> 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.
