Struct DiffOptions 

pub struct DiffOptions {
    pub parent_manifest_hash: Option<String>,
    pub ignore_hashes: bool,
    pub preserve_runnable: bool,
}

Options controlling the DIFF operation (diff_snapshots).

Fields

parent_manifest_hash: Option<String>

Hash of the parent manifest to record in the diff’s parent_manifest_hash field. The caller computes this from the parent’s serialized form.

ignore_hashes: bool

If true, ignore hash/chunk_hashes when comparing entries and skip the hash-state compatibility check. Useful for fast diffs where only metadata (size, mtime, runnable) is compared.

preserve_runnable: bool

If true, the runnable field is treated specially when a file appears in both snapshots:

1. Comparison: runnable is ignored when deciding whether the file changed (so a Windows collector that lost the POSIX execute bit does not cause a spurious “modified” entry).
2. Preservation: if the file is otherwise modified (size, mtime, or hash differs), the parent entry’s runnable value is copied into the diff entry instead of the current entry’s value.

The comparison half is delegated to entries_differ via its ignore_runnable parameter; the preservation half is applied by diff_snapshots itself when it emits the diff entry.

Trait Implementations

impl Default for DiffOptions

fn default() -> DiffOptions
