Metadata for a file to be written

Implementations

impl FileOptions

pub fn default() -> FileOptions

Construct a new FileOptions object

pub fn compression_method(self, method: CompressionMethod) -> FileOptions

Set the compression method for the new file

The default is CompressionMethod::Deflated. If the deflate compression feature is disabled, CompressionMethod::Stored becomes the default.

pub fn compression_level(self, level: Option<i32>) -> FileOptions

Set the compression level for the new file

None value specifies default compression level.

Range of values depends on compression method:

Deflated: 0 - 9. Default is 6
Bzip2: 0 - 9. Default is 6
Zstd: -7 - 22, with zero being mapped to default level. Default is 3
others: only None is allowed

pub fn last_modified_time(self, mod_time: DateTime) -> FileOptions

Set the last modified time

The default is the current timestamp if the ‘time’ feature is enabled, and 1980-01-01 otherwise

pub fn unix_permissions(self, mode: u32) -> FileOptions

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

pub fn large_file(self, large: bool) -> FileOptions

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. 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.
