Struct FilterOptions

#[non_exhaustive]
pub struct FilterOptions {
    pub level: LogLevel,
    pub filter: Vec<TargetLevel>,
}

Options for filtering logs.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

level: LogLevel

The default log level for anything that does not match an include or exclude filter.

filter: Vec<TargetLevel>

The targets and their log levels.

Implementations

impl FilterOptions

pub fn new(level: LogLevel, filter: Vec<TargetLevel>) -> Self

Create a new instance with the given log level.

Trait Implementations

impl Clone for FilterOptions

fn clone(&self) -> FilterOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FilterOptions

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

Formats the value using the given formatter.

impl Default for FilterOptions

fn default() -> Self

Returns the “default value” for a type.

impl<S> Filter<S> for FilterOptions

where S: Subscriber + for<'lookup> LookupSpan<'lookup>,

fn enabled(&self, metadata: &Metadata<'_>, _cx: &Context<'_, S>) -> bool

Returns true if this layer is interested in a span or event with the given Metadata in the current Context, similarly to Subscriber::enabled.

fn event_enabled(&self, event: &Event<'_>, _cx: &Context<'_, S>) -> bool

Called before the filtered [Layer]'s [on_event], to determine if on_event` should be called.

fn callsite_enabled(&self, meta: &'static Metadata<'static>) -> Interest

Returns an Interest indicating whether this layer will always, sometimes, or never be interested in the given Metadata.

fn max_level_hint(&self) -> Option<LevelFilter>

Returns an optional hint of the highest verbosity level that this Filter will enable.

fn on_new_span(&self, attrs: &Attributes<'_>, id: &Id, ctx: Context<'_, S>)

Notifies this filter that a new span was constructed with the given Attributes and Id.

fn on_record(&self, id: &Id, values: &Record<'_>, ctx: Context<'_, S>)

Notifies this filter that a span with the given Id recorded the given values.

fn on_enter(&self, id: &Id, ctx: Context<'_, S>)

Notifies this filter that a span with the given ID was entered.

fn on_exit(&self, id: &Id, ctx: Context<'_, S>)

Notifies this filter that a span with the given ID was exited.

fn on_close(&self, id: Id, ctx: Context<'_, S>)

Notifies this filter that a span with the given ID has been closed.
