Enum otter_nodejs_tests::zipfile::CompressionMethod

[−]

#[non_exhaustive]
pub enum CompressionMethod {
    Stored,
    Deflated,
    Bzip2,
    Aes,
    Zstd,
    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 crate::write::FileOptions::compression_method

Variants (Non-exhaustive)

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

`Stored`

Store the file as is

`Deflated`

Compress the file using Deflate

`Bzip2`

Compress the file using BZIP2

`Aes`

Encrypted using AES.

The actual compression method has to be taken from the AES extra data field or from ZipFileData.

`Zstd`

Compress the file using ZStandard

`Unsupported(u16)`

👎 Deprecated since 0.5.7:

use the constants instead

Unsupported compression method
