Struct FileAuditSink 

pub struct FileAuditSink { /* private fields */ }

File-based audit sink that writes JSONL (one JSON line per event).

Supports optional cryptographic chaining — when enabled, each event includes the SHA-256 hash of the previous event’s JSON representation, creating an append-only tamper-evident log.

Implementations

impl FileAuditSink

pub fn new(path: impl Into<PathBuf>) -> Result<Self, Error>

Create a new file audit sink.

pub fn with_chaining(path: impl Into<PathBuf>) -> Result<Self, Error>

Create a new file audit sink with cryptographic hash chaining enabled.

Each event will include a prev_hash field containing the SHA-256 hash of the previous event’s JSON, creating a tamper-evident append-only log.

pub fn path(&self) -> &PathBuf

Get the path to the audit log file.
