Struct AuditLog 

pub struct AuditLog {
    pub version: u32,
    pub entries: Vec<AuditEntry>,
}

Tamper-evident audit log with hash chain

Fields

version: u32

Log format version

entries: Vec<AuditEntry>

All entries in chronological order

Implementations

impl AuditLog

pub fn new() -> Self

Create a new empty audit log

pub fn record(&mut self, operation: AuditOperation) -> String

Record a new operation in the audit log

Returns the hash of the new entry.

pub fn verify_integrity(&self) -> bool

Verify the integrity of the entire hash chain

Returns true if all hashes are valid and the chain is intact.

pub fn verify_integrity_detailed(&self) -> IntegrityReport

Verify integrity and return detailed results

pub fn len(&self) -> usize

Get the number of entries in the log

pub fn is_empty(&self) -> bool

Check if the log is empty (has only the initial entry)

pub fn head_hash(&self) -> Option<&str>

Get the hash of the latest entry (chain head)

pub fn filter_by_type<F>(&self, predicate: F) -> Vec<&AuditEntry>

where F: Fn(&AuditOperation) -> bool,

Get entries filtered by operation type

pub fn filter_by_time(&self, start: u64, end: u64) -> Vec<&AuditEntry>

Get entries in a time range (inclusive)

pub fn save(&self, path: &Path) -> Result<(), EmbedError>

Save the audit log to a file (JSON format)

pub fn save_jsonl(&self, path: &Path) -> Result<(), EmbedError>

Save as newline-delimited JSON (each entry on one line)

This format is more suitable for streaming and appending.

pub fn load(path: &Path) -> Result<Self, EmbedError>

Load an audit log from a file (JSON format)

pub fn append_entry_to_file( path: &Path, entry: &AuditEntry, ) -> Result<(), EmbedError>

Append a single entry to an existing JSONL file

This is more efficient than rewriting the entire file.
