Struct serif::Config

pub struct Config { /* private fields */ }

Builder style configuration for the serif tracing-subscriber implementation.

Implementations

impl Config

pub fn new() -> Self

Create a new Config with the default configuration.

pub fn with_output(self, output: Output) -> Self

Change the output destination to stdout or stderr. The default is stdout.

pub fn with_color(self, color: ColorMode) -> Self

Enable or disable ANSI coloring. The default is ColorMode::Auto.

pub fn with_default(self, default: impl Into<Directive>) -> Self

Set the default log directive. The default is the INFO level.

You can call this with tracing::Level and tracing_subscriber::filter::LevelFilter, since those types implement Into<Directive>.

pub fn with_verbosity(self, verbosity: i32) -> Self

Set the default log level using a numberic “verbosity” value.

Applications can use this to easily turn the count of command line flags (e.g. --verbose or --quiet) into a default log level. This method does the same thing as Config::with_default and it makes no sense to combine them.

The mapping of verbosity levels to log levels is:

• -3 or less: off (no logs enabled)
• -2: error
• -1: warning
• 0: info
• 1: debug
• 2 or greater: trace

pub fn with_timestamp(self, time_format: TimeFormat) -> Self

Set the timestamp format for this Config.

pub fn with_target(self, display_target: bool) -> Self

Set whether or not an event’s target is displayed.

pub fn with_scope(self, display_scope: bool) -> Self

Set whether or not an event’s span scope is displayed.

pub fn init(self)

Finalize this Config and register it as the global default tracing subscriber.

Panics

Panics if the RUST_LOG environment variable is invalid (see make_env_filter) or if another global subscriber is already installed (see SubscriberBuilder::init).

pub fn make_env_filter(&self) -> EnvFilter

Create an EnvFilter from this Config.

Panics

Panics if the RUST_LOG environment variable contains invalid unicode, or if it contains invalid EnvFilter directives.
