Struct tokio_tar::GnuExtSparseHeader

#[repr(C)]
pub struct GnuExtSparseHeader { pub sparse: [GnuSparseHeader; 21], pub isextended: [u8; 1], pub padding: [u8; 7], }
Expand description

Representation of the entry found to represent extended GNU sparse files.

When a GnuHeader has the isextended flag set to 1 then the contents of the next entry will be one of these headers.

Implementations§

source§

impl GnuExtSparseHeader

source

pub fn new() -> GnuExtSparseHeader

Crates a new zero’d out sparse header entry.

source

pub fn as_bytes(&self) -> &[u8; 512]

Returns a view into this header as a byte array.

source

pub fn as_mut_bytes(&mut self) -> &mut [u8; 512]

Returns a view into this header as a byte array.

source

pub fn sparse(&self) -> &[GnuSparseHeader; 21]

Returns a slice of the underlying sparse headers.

Some headers may represent empty chunks of both the offset and numbytes fields are 0.

source

pub fn is_extended(&self) -> bool

Indicates if another sparse header should be following this one.
