Struct tracing_subscriber::fmt::format::FmtSpan

pub struct FmtSpan(_);

This is supported on crate feature fmt only.

Configures what points in the span lifecycle are logged as events.

See also with_span_events.

Implementations

impl FmtSpan

pub const NONE: FmtSpan

spans are ignored (this is the default)

pub const ACTIVE: FmtSpan

one event per enter/exit of a span

pub const CLOSE: FmtSpan

one event when the span is dropped

pub const FULL: FmtSpan

events at all points (new, enter, exit, drop)

Trait Implementations

impl Clone for FmtSpan

fn clone(&self) -> FmtSpan

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FmtSpan

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

Formats the value using the given formatter.

impl Eq for FmtSpan

impl Ord for FmtSpan

fn cmp(&self, other: &FmtSpan) -> Ordering

This method returns an Ordering between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp #44095)

Restrict a value to a certain interval.

impl PartialEq<FmtSpan> for FmtSpan

fn eq(&self, other: &FmtSpan) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &FmtSpan) -> bool

This method tests for !=.

impl PartialOrd<FmtSpan> for FmtSpan

fn partial_cmp(&self, other: &FmtSpan) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &FmtSpan) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &FmtSpan) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &FmtSpan) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &FmtSpan) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
