Struct AccountabilityLedger 

pub struct AccountabilityLedger { /* private fields */ }

An append-only, tamper-evident ledger of accountability records.

Implementations

impl AccountabilityLedger

pub fn new() -> Self

pub fn entries(&self) -> &[LedgerEntry]

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn head_hash(&self) -> String

The hash the next appended entry will chain to (the last entry’s hash, or genesis).

pub fn append( &mut self, kind: impl Into<String>, payload_json: impl Into<String>, signer: &SigningKey, time_unix: u64, ) -> &LedgerEntry

Append a record, signed by signer and chained to the current head. Returns the new entry.

pub fn verify(&self) -> Result<(), LedgerTamper>

Verify the whole chain: every entry’s content hash recomputes, chains to the previous, its sequence is in order, and its signature verifies. Returns the first tamper found, or Ok(()).

pub fn of_kind<'a>(&'a self, kind: &str) -> Vec<&'a LedgerEntry>

Entries of a given kind (e.g. all "conduct"), preserving order.

Trait Implementations

impl Clone for AccountabilityLedger

fn clone(&self) -> AccountabilityLedger

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AccountabilityLedger

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

Formats the value using the given formatter.

impl Default for AccountabilityLedger

fn default() -> AccountabilityLedger

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AccountabilityLedger

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AccountabilityLedger

fn eq(&self, other: &AccountabilityLedger) -> 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.

impl Serialize for AccountabilityLedger

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
