Struct ProcMacro

pub struct ProcMacro {
    pub kind: MacroKind,
    pub helpers: Vec<String>,
}

A procedural macro.

Fields

kind: MacroKind

How this macro is supposed to be called: foo!(), #[foo] or #[derive(foo)]

helpers: Vec<String>

Helper attributes defined by a macro to be used inside it.

Defined only for derive macros.

E.g. the Default derive macro defines a #[default] helper attribute so that one can do:

#[derive(Default)]
enum Option<T> {
    #[default]
    None,
    Some(T),
}

Trait Implementations

impl Clone for ProcMacro

fn clone(&self) -> ProcMacro

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ProcMacro

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ProcMacro

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for ProcMacro

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ProcMacro

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ProcMacro

impl StructuralPartialEq for ProcMacro

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
