Implementations

impl<T: ISO9660Reader> ISODirectory<T>

pub fn block_count(&self) -> u32

Returns the number of BLOCK_SIZE byte blocks required to contain the directory entry.

pub fn read_entry_at( &self, block: &mut BlockBuffer, buf_block_num: &mut Option<u64>, offset: u64 ) -> Result<(DirectoryEntry<T>, Option<u64>)>

I’m pretty sure this doesn’t need to be public and IsoFuse should just use contents() instead.

pub fn contents(&self) -> ISODirectoryIterator<'_, T>

Returns a ISODirectoryIterator, akin to POSIX.1’s readdir.

pub fn find(&self, identifier: &str) -> Result<Option<DirectoryEntry<T>>>

Returns the DirectoryEntry of the matching child

Arguments

• identifier - A valid path segment

Errors

Returns an error variant if there is an I/O error reading a directory entry. Returns Ok(None) if the path specified by identifer cannot be found.

pub fn find_recursive(&self, path: &str) -> Result<Option<DirectoryEntry<T>>>

Returns the DirectoryEntry matching the specified path. Similar to find but takes a full path and recurses through the descendants instead of a single path segment.

pub fn is_rock_ridge(&self) -> bool

Returns true if Rock Ridge extensions have been detected.

Trait Implementations

impl<T: ISO9660Reader> Clone for ISODirectory<T>

fn clone(&self) -> ISODirectory<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: ISO9660Reader> Debug for ISODirectory<T>

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: ISO9660Reader> ExtraAttributes for ISODirectory<T>

fn ext(&self) -> &ExtraMeta

Returns the ExtraMeta attached to the current object. Generally not something to be called directly.

fn header(&self) -> &DirectoryEntryHeader

Returns the DirectoryEntryHeader attached to the current object. Generally not something to be called directly.

fn relocated(&self) -> bool

Returns true if this directory has been relocated elsewhere to circumvent ISO 9660’s limits on directory depth.

fn time(&self) -> OffsetDateTime

Returns the ISO 9660 “recording” timestamp.

fn owner(&self) -> Option<u32>

Returns the file owner’s user ID (st_uid), if available.

fn group(&self) -> Option<u32>

Returns the file owner’s group ID (st_gid), if available.

fn mode(&self) -> Option<PosixFileMode>

Returns the file protection mode / Unix permissions (a.k.a. st_mode), if available.

fn access_time(&self) -> OffsetDateTime

Returns the last time the file contents were accessed (st_atime), if available. If there is no access time available, the value of time() is returned.

fn attribute_change_time(&self) -> OffsetDateTime

Returns the last time the attributes were changed (st_ctime), if available. If there is no ctime available, the value of time() is returned.

fn backup_time(&self) -> OffsetDateTime

Returns the last backup time, if available. If there is no backup time available, the value of time() is returned.

fn create_time(&self) -> OffsetDateTime

Returns the creation time, if available. If there is no creation time available, the value of time() is returned.

fn effective_time(&self) -> OffsetDateTime

Returns the effective time, if available. If there is no expiration time available, the value of time() is returned.

fn expire_time(&self) -> OffsetDateTime

Returns the expiration time, if available. If there is no expiration time available, the value of time() is returned.

fn modify_time(&self) -> OffsetDateTime

Returns the last modification time (st_mtime), if available. If there is no modification time available, the value of time() is returned.

fn inode(&self) -> Option<u32>

Returns the serial number (a.k.a. inode), if available.
