CopyDir Dir copies a whole directory recursively.

CopyWithCtx slightly modified function signature: - context has been added in order to propagate cancellation - I do not return the number of bytes written, has it is not useful in my use case.

GetNoneEmpty returns the first non-empty string, return empty if all empty.

HashData get hash of one hashType.

HashFile get hash of one hashType from a model.File.

HashReader get hash of one hashType from a reader.

NewMultiHasher will return a hash writer that will write the requested hash types.

PathAddSeparatorSuffix Add path '/' suffix for example /root => /root/.

PathEqual judge path is equal.

RegisterHash adds a new Hash to the list and returns its Type.

SliceAllContains check if slice all contains elements.

SliceContains check if slice contains element.

SliceConvert convert slice to another type slice.

SliceEqual check if two slices are equal.

SymlinkOrCopyFile symlinks a file or copy if symlink failed.

WriteJsonToFile write struct to json file.

ErrUnsupported should be returned by filesystem, if it is requested to deliver an unsupported hash type.

MD5 indicates MD5 support.

SHA1 indicates SHA-1 support.

SHA256 indicates SHA-256 support.

A HashInfo contains hash string for one or more hashType.

HashType indicates a standard hashing algorithm.

A MultiHasher will construct various hashes on all incoming writes.
