casync-rs

Experimental: Pure rust implementation of casync https://github.com/systemd/casync

Very minimal implementation of casync tool.

Command Usage

input file will be chunked, index.caidx and default.castr is created with chunks.

casync-rs make --file input

Expects index.caidx and default.castr directory to be present to construct out file from the chunks and index.

casync-rs extract --file out

Expects default.castr present with chunks corresponding to index.caidx file to construct the out file.

casync-rs extract -i index.caidx --file out

Created default.castr directory and download chunks to it, followed by construction of out file from the given index.caidx file.

casync-rs extract -i index.caidx -s http://0.0.0.0:8000/ --file out

Creates out file from /index.caidx and /default.castr endpoint from remote store to construct out file.

casync-rs extract -i http://0.0.0.0:8000/index.caidx -s http://0.0.0.0:8000/ --file out

Default minimum chunk size: 512KB and maximum chunk size: 1024KB

Test scenario

• Run python -m http_server which runs http server on 8000 port
• In a different folder run --extract to create artifact. store and index file are also created in the same folder
