Define a trait.

Implementations

impl Trait

pub fn new(name: impl Into<String>) -> Self

Return a trait definition with the provided name

pub fn ty(&self) -> &Type

Returns a reference to the type

pub fn vis(&mut self, vis: &str) -> &mut Self

Set the trait visibility.

pub fn attr(&mut self, attr: impl Into<String>) -> &mut Self

Attr

pub fn generic(&mut self, name: &str) -> &mut Self

Add a generic to the trait

pub fn bound<T>(&mut self, name: &str, ty: T) -> &mut Selfwhere
    T: Into<Type>,

Add a where bound to the trait.

pub fn macro(&mut self, macro: &str) -> &mut Self

Add a macro to the trait def (e.g. "#[async_trait]")

pub fn parent<T>(&mut self, ty: T) -> &mut Selfwhere
    T: Into<Type>,

Add a parent trait.

pub fn doc(&mut self, docs: &str) -> &mut Self

pub fn associated_const<T>(
    &mut self,
    name: impl Into<String>,
    ty: T
) -> &mut AssociatedConstwhere
    T: Into<Type>,

pub fn new_fn(&mut self, name: impl Into<String>) -> &mut Function

Push a new function definition, returning a mutable reference to it.

pub fn push_fn(&mut self, item: Function) -> &mut Self

Push a function definition.

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

Formats the scope using the given formatter.
