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.
Fields§
§sparse: [GnuSparseHeader; 21]
§isextended: [u8; 1]
§padding: [u8; 7]
Implementations§
source§impl GnuExtSparseHeader
impl GnuExtSparseHeader
sourcepub fn new() -> GnuExtSparseHeader
pub fn new() -> GnuExtSparseHeader
Crates a new zero’d out sparse header entry.
sourcepub fn as_mut_bytes(&mut self) -> &mut [u8; 512]
pub fn as_mut_bytes(&mut self) -> &mut [u8; 512]
Returns a view into this header as a byte array.
sourcepub fn sparse(&self) -> &[GnuSparseHeader; 21]
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.
sourcepub fn is_extended(&self) -> bool
pub fn is_extended(&self) -> bool
Indicates if another sparse header should be following this one.
