Struct tracing_subscriber::fmt::Subscriber[][src]

pub struct Subscriber<N = DefaultFields, E = Format<Full>, F = LevelFilter, W = fn() -> Stdout> { /* fields omitted */ }

A Subscriber that logs formatted representations of tracing events.

This consists of an inner Formatter wrapped in a layer that performs filtering.

Implementations

impl Subscriber[src]

pub const DEFAULT_MAX_LEVEL: LevelFilter[src]

The maximum verbosity level that is enabled by a Subscriber by default.

This can be overridden with the SubscriberBuilder::with_max_level method.

pub fn builder() -> SubscriberBuilder[src]

Returns a new SubscriberBuilder for configuring a format subscriber.

pub fn new() -> Self[src]

Returns a new format subscriber with the default configuration.
