Struct bevy::log::tracing_subscriber::FmtSubscriber
pub struct FmtSubscriber<N = DefaultFields, E = Format, F = LevelFilter, W = fn() -> Stdout> { /* private fields */ }
Expand description
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
impl Subscriber
pub const DEFAULT_MAX_LEVEL: LevelFilter = LevelFilter::INFO
Available on crate features fmt
and std
only.
pub const DEFAULT_MAX_LEVEL: LevelFilter = LevelFilter::INFO
fmt
and std
only.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
Available on crate features fmt
and std
only.
pub fn builder() -> SubscriberBuilder
fmt
and std
only.Returns a new SubscriberBuilder
for configuring a format subscriber.
pub fn new() -> Subscriber
Available on crate features fmt
and std
only.
pub fn new() -> Subscriber
fmt
and std
only.Returns a new format subscriber with the default configuration.
