Enum InitialContents

pub enum InitialContents<'a> {
    FromCapacity(u64),
    FromBufferAndCapactity(u64, &'a [u8]),
    FromBuffer(&'a [u8]),
    FromVmo(Vmo),
}

The initial contents of the VMO. This also determines the size of the block device.

Variants

FromCapacity(u64)

An empty VMO will be created with capacity for this many blocks.

FromBufferAndCapactity(u64, &'a [u8])

A VMO is created with capacity for this many blocks and the buffer’s contents copied into it.

FromBuffer(&'a [u8])

A VMO is created which is exactly large enough for the initial contents (rounded up to block size), and the buffer’s contents copied into it.

FromVmo(Vmo)

The provided VMO is used. If its size is not block-aligned, the data will be truncated.
