fn anon(size: u64) -> Result<Self, Self::Error>
where Self: Sized,

Creates a new shared memory file descriptor without specifying a name.

source

fn size(&self) -> u64

Gets the size in bytes of the shared memory.

The size returned here does not reflect changes by other interfaces or users of the shared memory file descriptor..
