Attribute Macro pin_init::pin_init [−][src]
#[pin_init]
Expand description
Mark a type as being init_pin!
-able.
Can only be applied to structs. Each field can be tagged with #[pin]
or not. Tagged fields are pin-initialized, and untaged fields are initialized
by value like they do in normal struct expression.
#[pin_init]
struct ManyPin {
#[pin]
a: NeedPin,
b: usize,
}
Also works for tuple-structs:
#[pin_init]
struct ManyPin(#[pin] NeedPin, usize);
You could apply it to unit-structs (but probably not very useful):
#[pin_init]
struct NoPin;
