Struct ApfsVolume 

pub struct ApfsVolume<R: Read + Seek> { /* private fields */ }

High-level read-only APFS volume reader

Implementations

impl<R: Read + Seek> ApfsVolume<R>

pub fn open(reader: R) -> Result<Self>

Open an APFS container and mount the first volume.

1. Read block 0 → parse NX superblock, validate NXSB magic + Fletcher-64
2. Scan checkpoint descriptor area for latest valid NX superblock
3. Read container OMAP at omap_oid physical block
4. Find first non-zero OID in fs_oids array
5. Resolve volume OID → physical block via container OMAP
6. Parse volume superblock (APSB magic)
7. Read volume OMAP at vol.omap_oid physical block
8. Resolve vol.root_tree_oid → physical block via volume OMAP → catalog B-tree root
9. Store all state

pub fn volume_info(&self) -> &VolumeInfo
