Struct tracing_subscriber::fmt::format::FmtSpan

pub struct FmtSpan(/* private fields */);

Available on crate features fmt and std only.

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

See also with_span_events.

Implementations

impl FmtSpan

pub const NEW: FmtSpan = _

one event when span is created

pub const ENTER: FmtSpan = _

one event per enter of a span

pub const EXIT: FmtSpan = _

one event per exit of a span

pub const CLOSE: FmtSpan = _

one event when the span is dropped

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 FULL: FmtSpan = _

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

Trait Implementations

impl BitAnd for FmtSpan

type Output = FmtSpan

The resulting type after applying the & operator.

fn bitand(self, rhs: Self) -> Self::Output

Performs the & operation.

impl BitAndAssign for FmtSpan

fn bitand_assign(&mut self, rhs: Self)

Performs the &= operation.

impl BitOr for FmtSpan

type Output = FmtSpan

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self::Output

Performs the | operation.

impl BitOrAssign for FmtSpan

fn bitor_assign(&mut self, rhs: Self)

Performs the |= operation.

impl BitXor for FmtSpan

type Output = FmtSpan

The resulting type after applying the ^ operator.

fn bitxor(self, rhs: Self) -> Self::Output

Performs the ^ operation.

impl BitXorAssign for FmtSpan

fn bitxor_assign(&mut self, rhs: Self)

Performs the ^= operation.

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 Ord for FmtSpan

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq 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: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd 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: &Rhs) -> bool

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

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

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

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

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

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

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