Methods

impl GnuHeader

fn username_bytes(&self) -> &[u8]

See Header::username_bytes

fn set_username(&mut self, name: &str) -> Result<()>

See Header::set_username

fn groupname_bytes(&self) -> &[u8]

See Header::groupname_bytes

fn set_groupname(&mut self, name: &str) -> Result<()>

See Header::set_groupname

fn device_major(&self) -> Result<u32>

See Header::device_major

fn set_device_major(&mut self, major: u32)

See Header::set_device_major

fn device_minor(&self) -> Result<u32>

See Header::device_minor

fn set_device_minor(&mut self, minor: u32)

See Header::set_device_minor

fn atime(&self) -> Result<u64>

Returns the last modification time in Unix time format

fn set_atime(&mut self, atime: u64)

Encodes the atime provided into this header.

Note that this time is typically a number of seconds passed since January 1, 1970.

fn ctime(&self) -> Result<u64>

Returns the last modification time in Unix time format

fn set_ctime(&mut self, ctime: u64)

Encodes the ctime provided into this header.

Note that this time is typically a number of seconds passed since January 1, 1970.

fn real_size(&self) -> Result<u64>

Returns the "real size" of the file this header represents.

This is applicable for sparse files where the returned size here is the size of the entire file after the sparse regions have been filled in.

fn is_extended(&self) -> bool

Indicates whether this header will be followed by additional sparse-header records.

Note that this is handled internally by this library, and is likely only interesting if a raw iterator is being used.
