Struct OnDiskDirEntry

Source
pub struct OnDiskDirEntry<'a> { /* private fields */ }
Expand description

Represents a 32-byte directory entry as stored on-disk in a directory file.

Implementations§

Source§

impl<'a> OnDiskDirEntry<'a>

Represents the 32 byte directory entry. This is the same for FAT16 and FAT32 (except FAT16 doesn’t use first_cluster_hi).

Source

pub fn raw_attr(&self) -> u8

Get the value from the $name field

Source

pub fn create_time(&self) -> u16

Get the value from the $name field

Source

pub fn create_date(&self) -> u16

Get the value from the $name field

Source

pub fn last_access_data(&self) -> u16

Get the value from the $name field

Source

pub fn first_cluster_hi(&self) -> u16

Get the value from the $name field

Source

pub fn write_time(&self) -> u16

Get the value from the $name field

Source

pub fn write_date(&self) -> u16

Get the value from the $name field

Source

pub fn first_cluster_lo(&self) -> u16

Get the value from the $name field

Source

pub fn file_size(&self) -> u32

Get the $name field

Source

pub fn new(data: &[u8]) -> OnDiskDirEntry<'_>

Create a new on-disk directory entry from a block of 32 bytes read from a directory file.

Source

pub fn is_end(&self) -> bool

Is this the last entry in the directory?

Source

pub fn is_valid(&self) -> bool

Is this a valid entry?

Source

pub fn is_lfn(&self) -> bool

Is this a Long Filename entry?

Source

pub fn lfn_contents(&self) -> Option<LfnEntry>

If this is an LFN, get the contents so we can re-assemble the filename.

Source

pub fn matches(&self, sfn: &ShortFileName) -> bool

Does this on-disk entry match the given filename?

Source

pub fn first_cluster_fat32(&self) -> ClusterId

Which cluster, if any, does this file start at? Assumes this is from a FAT32 volume.

Source

pub fn get_entry( &self, fat_type: FatType, entry_block: BlockIdx, entry_offset: u32, ) -> DirEntry

Convert the on-disk format into a DirEntry
