Struct AffsReaderVar 

pub struct AffsReaderVar<'a, D: SectorDevice> { /* private fields */ }

Variable block size AFFS reader.

This reader supports AFFS filesystems with block sizes from 512 to 8192 bytes, as used on Amiga hard disk partitions. The block size is determined by probing the root block at different sizes until the checksum validates.

Implementations

impl<'a, D: SectorDevice> AffsReaderVar<'a, D>

pub fn new(device: &'a D, total_sectors: u64) -> Result<Self, AffsError>

Create a new variable block size AFFS reader.

This probes the filesystem to determine the block size by trying different block sizes until the root block checksum validates.

Arguments

• device - Sector device to read from
• total_sectors - Total number of 512-byte sectors on the device

pub const fn fs_type(&self) -> FsType

Get the filesystem type (OFS or FFS).

pub const fn fs_flags(&self) -> FsFlags

Get filesystem flags.

pub const fn root_block(&self) -> u32

Get the root block number.

pub const fn total_blocks(&self) -> u32

Get the total number of blocks.

pub const fn block_size(&self) -> usize

Get the block size in bytes.

pub const fn log_blocksize(&self) -> u8

Get the log2 block size (relative to 512).

pub fn disk_name(&self) -> &[u8]

Get the disk name (volume label) as bytes.

pub fn disk_name_str(&self) -> Option<&str>

Get the disk name (volume label) as a string (if valid UTF-8).

pub fn label(&self) -> &[u8]

Get the volume label (alias for disk_name).

pub fn label_str(&self) -> Option<&str>

Get the volume label as string (alias for disk_name_str).

pub const fn creation_date(&self) -> AmigaDate

Get the volume creation date.

pub const fn last_modified(&self) -> AmigaDate

Get the volume last modification date.

pub fn mtime(&self) -> i64

Get the volume modification time as Unix timestamp.

This matches GRUB’s grub_affs_mtime() behavior:

• days * 86400 + min * 60 + hz / 50 + epoch offset

pub const fn hash_table_size(&self) -> u32

Get the hash table size.

pub const fn is_intl(&self) -> bool

Check if international mode is enabled.

pub fn read_symlink( &self, block: u32, out: &mut [u8], ) -> Result<usize, AffsError>

Read a symlink target.

Arguments

• block - Block number of the symlink entry
• out - Buffer to write the UTF-8 symlink target into

Returns

The number of bytes written to out.

pub fn read_root_dir(&self) -> Result<VarDirIter<'_, D>, AffsError>

Iterate over entries in the root directory.

pub fn read_dir(&self, block: u32) -> Result<VarDirIter<'_, D>, AffsError>

Iterate over entries in a directory.
