Source
pub struct Impl { /* private fields */ }
Expand description

Defines an impl block.

Implementations§

Source§

impl Impl

Source

pub fn new<T>(target: T) -> Self
where T: Into<Type>,

Return a new impl definition

Source

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

Add a generic to the impl block.

This adds the generic for the block (impl<T>) and not the target type.

Source

pub fn target_generic<T>(&mut self, ty: T) -> &mut Self
where T: Into<Type>,

Add a generic to the target type.

Source

pub fn impl_trait<T>(&mut self, ty: T) -> &mut Self
where T: Into<Type>,

Set the trait that the impl block is implementing.

Source

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

Add a macro to the impl block (e.g. "#[async_trait]")

Source

pub fn associate_const<T>( &mut self, name: impl Into<String>, ty: T, value: impl Into<String>, visibility: impl Into<String>, ) -> &mut Self
where T: Into<Type>,

Set an associated constant.

Source

pub fn associate_type<T>(&mut self, name: &str, ty: T) -> &mut Self
where T: Into<Type>,

Set an associated type.

Source

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

Add a where bound to the impl block.

Source

pub fn new_fn(&mut self, name: &str) -> &mut Function

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

Source

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

Push a function definition.

Source

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

Formats the impl block using the given formatter.
