Variants

Memory

In-memory ring buffer — not persisted across restarts.

buffer: Vec<AuditRecord>

Fixed-size ring buffer of audit records.

position: usize

Write position in the ring.

File

Append-only JSON Lines file.

Fields

path: String

File path for audit records.

Implementations

impl AuditBackend

pub fn new_memory(capacity: usize) -> Self

Creates a memory-backed audit backend.

Arguments

• capacity: Maximum number of records in the ring buffer.

Returns

Returns an empty AuditBackend::Memory.

pub fn new_file(path: String) -> Self

Creates a file-backed audit backend.

Arguments

• path: Absolute path to the audit file.

Returns

Returns an AuditBackend::File.

pub fn from_config(config: &AuditConfig) -> Self

Creates an audit backend from configuration.

Arguments

• config: Audit configuration.

Returns

Returns the configured backend, defaulting to memory (4096 capacity) when no file path is provided.

pub fn write(&mut self, record: &AuditRecord) -> Result<(), DashboardError>

Writes an audit record to the backend.

Arguments

• record: The audit record to persist.

Returns

Returns Ok(()) when the write succeeds, or Err(DashboardError) on failure.

pub fn recent(&self, count: usize) -> Vec<AuditRecord>

Returns recent audit records (for inspection).

Arguments

• count: Maximum number of recent records to return.

Returns

Returns a vector of audit records, newest first.
