Struct tar::GnuExtSparseHeader
[−]
[src]
#[repr(C)]pub struct GnuExtSparseHeader { pub sparse: [GnuSparseHeader; 21], pub isextended: [u8; 1], pub padding: [u8; 7], }
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.
Fields
sparse: [GnuSparseHeader; 21]
isextended: [u8; 1]
padding: [u8; 7]
Methods
impl GnuExtSparseHeader[src]
pub fn new() -> GnuExtSparseHeader[src]
Crates a new zero'd out sparse header entry.
pub fn as_bytes(&self) -> &[u8; 512][src]
Returns a view into this header as a byte array.
pub fn as_mut_bytes(&mut self) -> &mut [u8; 512][src]
Returns a view into this header as a byte array.
pub fn sparse(&self) -> &[GnuSparseHeader; 21][src]
Returns a slice of the underlying sparse headers.
Some headers may represent empty chunks of both the offset and numbytes fields are 0.
pub fn is_extended(&self) -> bool[src]
Indicates if another sparse header should be following this one.
