pub fn get_table(&mut self) -> Result<BlkidParttable>

Get the partition table for a list of partitions.

pub fn get_partition(&mut self, index: c_int) -> Result<BlkidPartition>

Get a partition at the given index of the list.

pub fn get_partition_by_partno(&mut self, num: c_int) -> Result<BlkidPartition>

Get a partition by the number listed in the partition table. Correctly handles “out-of-order” partition tables.

pub fn get_partition_by_devno( &mut self, dev: &BlkidDevno ) -> Result<BlkidPartition>

Get a partition using the device number of a partition.
