pub const SECTOR_SIZE: i64 = 243;Expand description
Trytes per block-device sector: 3^5.
A size, not a stride: sectors tile the backing image with no gap, so sector
k covers bytes k * SECTOR_SIZE onward and the window holds exactly this
many trytes. The sector’s base within the device is
block::WINDOW.
Small enough that the window and the block device’s registers fit inside one
DEVICE_STRIDE slot.
