Struct NestedFrame 

pub struct NestedFrame<'a, 'b, A>
where
    A: AtomBody + ?Sized,
{ /* private fields */ }

A writing frame managing nested atoms.

Unlike the RootFrame, which really manages memory, this frame only forwards writing calls to the next frame in the hierarchy and updates the atom header accordingly. Additionally, this frame will assure for padding when dropped. These padding bytes will not be included in the top level header, only in the surrounding ones.

Nested frames can only be created with the create_nested_frame method.

Trait Implementations

impl<'a, 'b, A> Drop for NestedFrame<'a, 'b, A>

where A: AtomBody + ?Sized,

fn drop(&mut self)

Executes the destructor for this type.

impl<'a, 'b, A> WritingFrame<'b> for NestedFrame<'a, 'b, A>

where A: AtomBody + ?Sized,

unsafe fn write_raw(&mut self, data: &[u8]) -> Result<&'b mut [u8], ()>

Try to write out a slice of bytes into the atom space.

fn get_atom(&self) -> &Atom

Return an immutable reference to the managed atom header.

impl<'a, 'b, A: AtomBody + ?Sized> WritingFrameExt<'b, A> for NestedFrame<'a, 'b, A>

unsafe fn write_sized<T: Sized>(&mut self, object: &T) -> Result<&'a mut T, ()>

Try to write a sized object into the atom space.

unsafe fn create_nested_frame<'b, C: AtomBody + ?Sized>( &'b mut self, urids: &mut CachedMap, ) -> Result<NestedFrame<'b, 'a, C>, ()>

Create a new atom header and return a nested writing frame for it.

unsafe fn get_atom_body<'b>( &'b self, urids: &mut CachedMap, ) -> Result<&'b A, GetBodyError>

Try to get a reference to the body from our atom header.
