    unsafe fn claim_shared_bytes(

        start: *const u8, 
        len: usize, 
        type_id: TypeId

    ) -> Result<Option<*const T>, Self::Error>
    where
        Self: ArchiveBoundsContext,
        <T as Pointee>::Metadata: LayoutMetadata<T>,
    { ... }
}

A context that can validate shared archive memory.

Shared pointers require this kind of context to validate.

Required methods

unsafe fn claim_shared_bytes(
    &mut self,
    start: *const u8,
    len: usize,
    type_id: TypeId
) -> Result<bool, Self::Error>[src]

Claims count shared bytes located offset bytes away from base.

Returns whether the bytes need to be checked.

Safety

The caller must guarantee that base is inside the archive this context was created for.

Provided methods

fn claim_shared_ptr<T: ArchivePointee + CheckBytes<Self> + ?Sized>(
    &mut self,
    rel_ptr: &RelPtr<T>,
    type_id: TypeId
) -> Result<Option<*const T>, Self::Error> where
    Self: ArchiveBoundsContext,
    <T as Pointee>::Metadata: LayoutMetadata<T>, [src]

Claims the memory referenced by the given relative pointer.

If the pointer needs to be checked, returns Some with the pointer to check.
