Enum CompressionMethod

pub enum CompressionMethod {
    Stored,
    Deflated,
    Bzip2,
    Unsupported(u16),
}

Identifies the storage format used to compress a file within a ZIP archive.

Each file’s compression method is stored alongside it, allowing the contents to be read without context.

When creating ZIP files, you may choose the method to use with [zip::write::FileOptions::compression_method]

Variants

Stored

Store the file as is

Deflated

Compress the file using Deflate

Bzip2

Compress the file using BZIP2

Unsupported(u16)

👎Deprecated since 0.5.7: use the constants instead

Unsupported compression method

Converts an u16 to its corresponding CompressionMethod

pub fn to_u16(self) -> u16

👎Deprecated since 0.5.7: to match on other compression methods, use a constant

Converts a CompressionMethod to a u16

Trait Implementations

impl Clone for CompressionMethod

fn clone(&self) -> CompressionMethod

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CompressionMethod

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for CompressionMethod

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for CompressionMethod

fn eq(&self, other: &CompressionMethod) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
