Struct ExternBlock 

pub struct ExternBlock<Attr, Abi, Body> {
    pub attr: Attr,
    pub abi: Abi,
    pub body: Body,
}

Declaration of an extern block, i.e. for FFI. In Rust 2024 and later, the unsafe keyword must be added for extern blocks. Thus, this struct requires that the context satisfies [ContextProvides] for Edition.

Fields

attr: Attr

The attributes. Must be a sequence, and each value will be placed inside #[].

abi: Abi

The ABI chosen. Must be writable

body: Body

The body of the extern block. Must be writable

Trait Implementations

impl<Attr: Clone, Abi: Clone, Body: Clone> Clone for ExternBlock<Attr, Abi, Body>

fn clone(&self) -> ExternBlock<Attr, Abi, Body>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Attr: Debug, Abi: Debug, Body: Debug> Debug for ExternBlock<Attr, Abi, Body>

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

Formats the value using the given formatter.

impl<O, Attr, Abi, Body> Writable<O> for ExternBlock<Attr, Abi, Body>

where O: Output, O::Ctx: ContextProvides<Edition>, Attr: WritableSeq<O>, Abi: Writable<O>, Body: Writable<O>,

async fn write_to(&self, output: &mut O) -> Result<(), O::Error>

Writes to the output. Returns the output’s error upon failure.
