Enum ContentDigestMode 

pub enum ContentDigestMode {
    Strong,
    Strongish,
    Weak,
}

Represents the supported modes for calculating content digests.

Variants

Strong

Use a strong digest for file content.

Strong digests require hashing all of the contents of a file; this may noticeably impact performance for very large files.

This setting guarantees that a modified file will be detected.

Strongish

Use a “strongish” digest for file content.

A strongish digest is based off of the file’s size, last modified time, and a hash of only the first 10 MiB of the file’s contents; this is similar to Cromwell’s fingerprint call caching strategy.

This setting cannot guarantee the detection of modified files (e.g. a modification beyond the first 10 MiB of a file without a change to its size or last modified time will not be detected), but it is faster than using a strong digest for large files while still taking file content into account.

Weak

Use a weak digest for file content.

A weak digest is based solely off of file metadata, such as size and last modified time.

This setting cannot guarantee the detection of modified files and may result in a modified file not causing a call cache entry to be invalidated.

However, it is substantially faster than using a strong digest.
