Struct 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,

Restrict a value to a certain interval.

impl PartialEq for FmtSpan

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

Tests for self and other values to be equal, and is used by ==.

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
