Struct SaveFingerprint 

pub struct SaveFingerprint {
    pub hash: String,
    pub mod_ids: SmallVec<[String; 8]>,
}

A fingerprint of the save-breaking mods active when a save was captured.

Computed as SHA-256 over the sorted list of enabled, save-breaking mod IDs (and their versions). Two profiles with the same save-breaking mods produce the same fingerprint, regardless of cosmetic mod differences.

Stored as a Mod-Fingerprint: trailer in save vault commit messages.

Fields

hash: String

Hex-encoded SHA-256 hash (first 16 characters for display).

mod_ids: SmallVec<[String; 8]>

The save-breaking mod IDs that contributed to this fingerprint. Typically 5–15 mods; SmallVec<[_; 8]> keeps ≤8 inline (no heap allocation).

Implementations

impl SaveFingerprint

pub fn compute(mods: &[EnabledMod], classify: impl Fn(&str) -> bool) -> Self

Compute a fingerprint from a list of mods and a classification function.

classify takes a mod_id and returns whether it’s save-breaking. This is intentionally a callback so the caller can resolve staging paths and call GamePlugin::classify_mod — keeping modde-core independent of modde-games.

pub fn short_hash(&self) -> &str

Short hash for display (first 12 hex chars).

pub fn empty() -> Self

Empty fingerprint (no save-breaking mods).

pub fn is_empty(&self) -> bool

Trait Implementations

impl Clone for SaveFingerprint

fn clone(&self) -> SaveFingerprint

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SaveFingerprint

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for SaveFingerprint

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SaveFingerprint

fn eq(&self, other: &SaveFingerprint) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
