Provided Methods

fn get_hash<R>(reader: &mut R, hasher: &mut Sha384) -> Result<String, Error>

where R: Read,

compute the hash of the file pointed by the filepath by using io::copy between a file handler and the hasher. As such, it shouldn’t make the program go OOM with big files, but it has not been tested. Can return an error if there has been problems regarding IO.

fn get_hash_path(src: &Path, hasher: &mut Sha384) -> Result<String, Error>

corpus/lang/lang_part_x.jsonl

fn checksum_folder(src: &Path, num_threads: usize) -> Result<(), Error>

this should operate on the wide-level.

fn get_write_hashes(src: &Path) -> Result<(), Error>

convinience function for checksum_folder TODO: move out of trait

fn write_checksum<W: Write>( writer: &mut W, hashes: Vec<(PathBuf, String)>, ) -> Result<(), Error>

fn checksum_lang(src: &Path) -> Result<Vec<(PathBuf, String)>, Error>

this should operate on lang-level

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
