Enum WriteStrategy 

pub enum WriteStrategy {
    Create {
        output: CompressedPath,
    },
    Append {
        path: PathBuf,
    },
    CopyOnWrite {
        input: CompressedPath,

    AtomicSwap {
        path: PathBuf,
        compression: CompressionFormat,
        temp_path: PathBuf,
    },
}

Describes how to write archive data based on input/output paths and compression.

Variants

Create

Create a new archive from scratch. No existing archive to read.

Fields

output: CompressedPath

Append

Append to an existing uncompressed archive in-place. Just seek to end and write new records.

Fields

path: PathBuf

CopyOnWrite

Read from one location, write to another. Handles transcoding between compression formats.

Fields

input: CompressedPath

output: CompressedPath

AtomicSwap

Read compressed archive, write to temp, atomic swap. Required when source == dest AND compressed.

Fields

path: PathBuf

The archive path (both input and output)

compression: CompressionFormat

Compression format (same for input and output in this case)

temp_path: PathBuf

Temp file to write to before swapping
