Struct r3::hunk::HunkDefiner

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

The definer (static builder) for Hunk.

InitTag is either DefaultInitTag or ZeroInitTag.

Implementations

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

pub const fn len(self, len: usize) -> HunkDefiner<System, T, InitTag>

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

pub const fn align(self, align: usize) -> HunkDefiner<System, T, InitTag>

Specify the minimum alignment. Defaults to 1.

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

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

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

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

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

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

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