Struct sel4_async_block_io_fat::fat::InfoSector

pub struct InfoSector<'a> { /* private fields */ }

File System Information structure is only present on FAT32 partitions. It may contain a valid number of free clusters and the number of the next free cluster. The information contained in the structure must be considered as advisory only. File system driver implementations are not required to ensure that information within the structure is kept consistent.
