Implementations

impl LoggerSettings

pub fn from_opts<O: Opts>(opts: &O) -> Self

Create a new logger settings from the given command-line options.

If env var RW_TRACING_ENDPOINT is not set, the meta address will be used as the default tracing endpoint, which means that the embedded tracing collector will be used.

pub fn new(name: impl Into<String>) -> Self

Create a new logger settings with the given service name.

pub fn tokio_console(self, enabled: bool) -> Self

Enable tokio console output.

pub fn stderr(self, enabled: bool) -> Self

Output to stderr instead of stdout.

pub fn with_thread_name(self, enabled: bool) -> Self

Whether to include thread name in the log.

pub fn with_target( self, target: impl Into<String>, level: impl Into<LevelFilter>, ) -> Self

Overrides the default target settings.

pub fn with_default(self, level: impl Into<LevelFilter>) -> Self

Overrides the default level.

pub fn with_tracing_endpoint(self, endpoint: impl Into<String>) -> Self

Overrides the tracing endpoint.

Trait Implementations

impl Default for LoggerSettings

fn default() -> Self

Returns the “default value” for a type.
