Struct AllocationUnit 

pub struct AllocationUnit { /* private fields */ }

Net bytes per unit of whatever Status counts for a partition: 1 where the counters are byte-granular, the net storage block in a library.

See Partition::allocation_unit, which is the only source of one.

Implementations

impl AllocationUnit

pub fn get(self) -> u32

pub fn is_bytes(self) -> bool

Whether this partition’s counters are byte-granular rather than block-granular.

pub fn blocks_for(self, bytes: usize) -> Result<u32>

How many units a body of bytes occupies.

⚠️ Rounds up. Undercounting makes cmd::BEGIN_WRITE refuse 0x16 even straight after a cleaning pass that reclaimed what the undercount asked for.
