Enum CompressionMethod

#[non_exhaustive]pub enum CompressionMethod {
    Stored,
    Deflated,
    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

Unsupported(u16)

👎Deprecated since 0.5.7: use the constants instead

Unsupported compression method
