Implementations

impl LlmpMsg

The message we receive

pub unsafe fn as_slice_unsafe(&self) -> &[u8]

Gets the buffer from this message as slice, with the corrent length.

Safety

This is unsafe if somebody has access to shared mem pages on the system.

pub fn try_as_slice<SHM: ShMem>( &self, map: &mut LlmpSharedMap<SHM> ) -> Result<&[u8], Error>

Gets the buffer from this message as slice, with the correct length.

pub fn in_shmem<SHM: ShMem>(&self, map: &mut LlmpSharedMap<SHM>) -> bool

Returns true, if the pointer is, indeed, in the page of this shared map.
