Implementations

impl MacroDef

pub fn new(name: String, params: Vec<String>, body: String) -> Self

Create a new macro definition

pub fn arity(&self) -> usize

Validate that the macro definition is well-formed

pub fn expand(&self, args: &[String]) -> Result<String>

Expand the macro with the given arguments

Trait Implementations

impl Clone for MacroDef

fn clone(&self) -> MacroDef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MacroDef

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MacroDef

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MacroDef

fn eq(&self, other: &MacroDef) -> 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 MacroDef

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
