Struct cdfs::ExtraMeta

pub struct ExtraMeta {
    pub alt_name: Option<String>,
    pub attributes: Option<PosixAttributes>,
    pub symlink_target: Option<String>,
    pub extensions: HashSet<SuspExtension>,

Fields

alt_name: Option<String>

Used for e.g. Rock Ridge long filenames

This contains an alternative name picked up from an NM entry in the system use table. Joliet style filenames and ISO 9660 Level 3 filenames simply store the long filenames in the directory structures.

System Use Sharing Protocol § 4.1.4

attributes: Option<PosixAttributes>

POSIX attributes (permissions, ownership, links, inode)

This contains a PosixAttributes struct generated from a PX entry in the system use table.

See Also

System Use Sharing Protocol § 4.1.1

symlink_target: Option<String>

If the directory entry is a symbolic link, its target is stored here.

This contains a path specified by one or more SL entries in the system use table.

See Also

System Use Sharing Protocol § 4.1.3

extensions: HashSet<SuspExtension>

HashSet of all the system use extensions used by this directory hierarchy.

All SUSP-compliant extensions are required to include an ER entry in the system use table.

System Use Sharing Protocol § 5.5

timestamps: PosixTimestamp

POSIX style timestamps (access, creation, modification, etc.)

This field cotains the timestamps collected from one or more TF entries in the system use table.

Rock Ridge Interchange Protocol § 4.1.6

relocated: bool

True if this directory actually exists at another location.

To avoid misbehavior relocated directories should be hidden from view or given a distinct inode.

Trait Implementations

impl Clone for ExtraMeta

fn clone(&self) -> ExtraMeta

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExtraMeta

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

Formats the value using the given formatter.

impl Default for ExtraMeta

fn default() -> ExtraMeta

Returns the “default value” for a type.

impl PartialEq for ExtraMeta

fn eq(&self, other: &ExtraMeta) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
