Implementations
Source§impl<T: FileOptionExtension> FileOptions<'_, T>
impl<T: FileOptionExtension> FileOptions<'_, T>
Sourcepub const fn compression_method(self, method: CompressionMethod) -> Self
pub const fn compression_method(self, method: CompressionMethod) -> Self
Set the compression method for the new file
The default is CompressionMethod::Deflated
if it is enabled. If not,
CompressionMethod::Bzip2
is the default if it is enabled. If neither bzip2
nor deflate
is enabled, CompressionMethod::Zlib
is the default. If all else fails,
CompressionMethod::Stored
becomes the default and files are written uncompressed.
Sourcepub const fn compression_level(self, level: Option<i64>) -> Self
pub const fn compression_level(self, level: Option<i64>) -> Self
Set the compression level for the new file
None
value specifies default compression level.
Range of values depends on compression method:
Deflated
: 10 - 264 for Zopfli, 0 - 9 for other encoders. Default is 24 if Zopfli is the only encoder, or 6 otherwise.Bzip2
: 0 - 9. Default is 6Zstd
: -7 - 22, with zero being mapped to default level. Default is 3- others: only
None
is allowed
Sourcepub const fn last_modified_time(self, mod_time: DateTime) -> Self
pub const fn last_modified_time(self, mod_time: DateTime) -> Self
Set the last modified time
The default is the current timestamp if the ‘time’ feature is enabled, and 1980-01-01 otherwise
Sourcepub const fn unix_permissions(self, mode: u32) -> Self
pub const fn unix_permissions(self, mode: u32) -> Self
Set the permissions for the new file.
The format is represented with unix-style permissions.
The default is 0o644
, which represents rw-r--r--
for files,
and 0o755
, which represents rwxr-xr-x
for directories.
This method only preserves the file permissions bits (via a & 0o777
) and discards
higher file mode bits. So it cannot be used to denote an entry as a directory,
symlink, or other special file type.
Sourcepub const fn large_file(self, large: bool) -> Self
pub const fn large_file(self, large: bool) -> Self
Set whether the new file’s compressed and uncompressed size is less than 4 GiB.
If set to false
and the file exceeds the limit, an I/O error is thrown and the file is
aborted. If set to true
, readers will require ZIP64 support and if the file does not
exceed the limit, 20 B are wasted. The default is false
.
Sourcepub const fn with_zopfli_buffer(self, size: Option<usize>) -> Self
pub const fn with_zopfli_buffer(self, size: Option<usize>) -> Self
Sets the size of the buffer used to hold the next block that Zopfli will compress. The
larger the buffer, the more effective the compression, but the more memory is required.
A value of None
indicates no buffer, which is recommended only when all non-empty writes
are larger than about 32 KiB.
Sourcepub const fn get_compression_level(&self) -> Option<i64>
pub const fn get_compression_level(&self) -> Option<i64>
Returns the compression level currently set.
Sourcepub const fn with_alignment(self, alignment: u16) -> Self
pub const fn with_alignment(self, alignment: u16) -> Self
Sets the alignment to the given number of bytes.
