Struct PromptLogConfig 

pub struct PromptLogConfig {
    pub enabled: bool,
    pub dir: PathBuf,
    pub max_bytes: u64,
    pub retention_days: u32,
    pub hash_prompts: bool,
}

Configuration for PromptLogger.

Why: keeps env-parsing out of the hot path and allows tests to construct loggers directly without mutating process-wide env state. The struct is Clone so a logger can be cheaply re-derived per invocation. What: holds the resolved log directory, size cap, retention window, and privacy toggles. enabled = false short-circuits every write. Test: covered by config_from_env_disabled and the integration tests.

Fields

enabled: bool

Master enable switch. false → every method is a no-op.

dir: PathBuf

Directory holding the rolling log files (created lazily on first write).

max_bytes: u64

Per-file size cap; the writer rolls to a new numeric suffix when the active file would exceed this size.

retention_days: u32

Retention window in days. Files older than this are pruned on the first write of each day.

hash_prompts: bool

Replace trigger_prompt field bodies with sha256:<hex> when true.

Implementations

impl PromptLogConfig

pub fn from_env_with_root(data_root: &Path) -> Self

Build a config rooted at the supplied data_root and overlayed with env vars.

Why: prompt-context and inbox-check both resolve their data root via trusty_common::resolve_data_dir but only that caller knows the app name. Accepting an explicit root lets the logger reuse the same resolution without parsing dirs::data_dir twice. What: defaults dir = data_root/logs; overrides via TRUSTY_MEMORY_* envs. enabled defaults to true; flips to false when TRUSTY_MEMORY_PROMPT_LOG is set to an off-value. Test: config_from_env_defaults, config_from_env_disabled, config_from_env_overrides_dir.
