Implementations§

source§

impl GnuHeader

source

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

See Header::username_bytes

source

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

See Header::set_username

source

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

See Header::groupname_bytes

source

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

See Header::set_groupname

source

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

See Header::device_major

source

pub fn set_device_major(&mut self, major: u32)

See Header::set_device_major

source

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

See Header::device_minor

source

pub fn set_device_minor(&mut self, minor: u32)

See Header::set_device_minor

source

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

Returns the last modification time in Unix time format

source

pub 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.

source

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

Returns the last modification time in Unix time format

source

pub 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.

source

pub 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.

source

pub 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.

source

pub fn as_header(&self) -> &Header

Views this as a normal Header

source

pub fn as_header_mut(&mut self) -> &mut Header

Views this as a normal Header
