Struct r3_core::hunk::HunkDefiner

pub struct HunkDefiner<System, T: ?Sized, InitTag> { /* private fields */ }

The definer (static builder) for Hunk.

InitTag is either DefaultInitTag or ZeroInitTag.

Implementations

impl<System: KernelBase + KernelStatic, T: ?Sized, InitTag> HunkDefiner<System, T, InitTag>

pub const fn len(self, len: usize) -> Self

Specify the element count. Defaults to 1. Must be 1 for a non-array hunk.

pub const fn align(self, align: usize) -> Self

Specify the minimum alignment. Defaults to 1.

pub const fn zeroed(self) -> HunkDefiner<System, T, ZeroInitTag>where T: Zeroable,

Zero-initialize the hunk.

pub const unsafe fn zeroed_unchecked( self ) -> HunkDefiner<System, T, ZeroInitTag>

Zero-initialize the hunk even if it might be unsafe.

Safety

If zero initialization is not a valid bit pattern for T, accessing the hunk’s contents may result in an undefined behavior.

impl<System: KernelBase + KernelStatic, T, InitTag: HunkIniter<T>> HunkDefiner<System, T, InitTag>

pub const fn finish<C: CfgBase<System = System>>( self, cfg: &mut Cfg<'_, C> ) -> Hunk<System, T>

Complete the definition of a hunk, returning a reference to the hunk.

impl<System: KernelBase + KernelStatic, T, InitTag: HunkIniter<T>> HunkDefiner<System, [T], InitTag>

pub const fn finish<C: CfgBase<System = System>>( self, cfg: &mut Cfg<'_, C> ) -> Hunk<System, [T]>

Complete the definition of a hunk, returning a reference to the hunk.
