file_path: Option<PathBuf>

Optional file path for rotating logs.

targets: BTreeMap<String, String>

Per-target log level overrides.

with_target: bool

Implementations

impl LogConfig

pub fn from_env(default_level: &str) -> Self

Build a logging configuration from environment variables.

Supported environment variables:

• RCH_LOG_LEVEL
• RCH_LOG_FORMAT (pretty|json|compact)
• RCH_LOG_FILE (path to rotating log file)
• RCH_LOG_TARGETS (comma-separated target=level list)

pub fn with_level(self, level: impl Into<String>) -> Self

Override the base log level.

pub fn with_stderr(self) -> Self

Write console logs to stderr.

pub fn env_filter(&self) -> EnvFilter

Build the effective EnvFilter, honoring RUST_LOG if set.

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

Performs copy-assignment from source.

impl Debug for LogConfig

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

Formats the value using the given formatter.

impl Default for LogConfig

fn default() -> Self
