#### fn clone(&self) -> MacroKind

Returns a duplicate of the value. Read more

Source§

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

Formats the value using the given formatter. Read more
Source§

### impl<'de> Deserialize<'de> for MacroKind

Source§

#### fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>
where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer. Read more
Source§

### impl Hash for MacroKind

Source§

Source§

### impl PartialEq for MacroKind

Source§

#### fn eq(&self, other: &MacroKind) -> bool

#### fn ne(&self, other: &Rhs) -> bool

Tests for `!=`. The default implementation is almost always sufficient, and should not be overridden without very good reason.

## 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.
