Macro kernel::stack_pin_init
source · macro_rules! stack_pin_init { (let $var:ident $(: $t:ty)? = $val:expr) => { ... }; }
Expand description
Initialize and pin a type directly on the stack.
§Examples
#[pin_data]
struct Foo {
#[pin]
a: Mutex<usize>,
b: Bar,
}
#[pin_data]
struct Bar {
x: u32,
}
stack_pin_init!(let foo = pin_init!(Foo {
a <- new_mutex!(42),
b: Bar {
x: 64,
},
}));
let foo: Pin<&mut Foo> = foo;
pr_info!("a: {}", &*foo.a.lock());
§Syntax
A normal let
binding with optional type annotation. The expression is expected to implement
PinInit
/Init
with the error type Infallible
. If you want to use a different error
type, then use stack_try_pin_init!
