Enum otter_api_tests::zipfile::CompressionMethod[−]

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

Expand description

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
