Struct MetaTemplate 

pub(crate) struct MetaTemplate(pub(crate) Box<[Op]>);

Consider

macro_rules! a_macro {
    ($x:expr, $y:expr) => ($y * $x)
}

Stuff to the left of => is a MetaTemplate pattern (which is matched with input).

Stuff to the right is a MetaTemplate template which is used to produce output.

Trait Implementations

impl Clone for MetaTemplate

fn clone(&self) -> MetaTemplate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetaTemplate

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

Formats the value using the given formatter.

impl PartialEq for MetaTemplate

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