Method from_path

src/blob.rs:150–159

Returns a [BlobObject] for an existing blob from a path. The path must designate a file directly in the blobdir and must use a valid blob name. That is after sanitisation the name must still be the same, that means it must be valid UTF-8 and not have any special characters in it.
