Implementations

impl InstrumentKind

pub fn synchronous(&self) -> bool

Whether this is a synchronous kind of instrument.

pub fn asynchronous(&self) -> bool

Whether this is a synchronous kind of instrument.

pub fn adding(&self) -> bool

Whether this kind of instrument adds its inputs (as opposed to grouping).

pub fn grouping(&self) -> bool

Whether this kind of instrument groups its inputs (as opposed to adding).

pub fn monotonic(&self) -> bool

Whether this kind of instrument exposes a non-decreasing sum.

pub fn precomputed_sum(&self) -> bool

Whether this kind of instrument receives precomputed sums.

Trait Implementations

impl Clone for InstrumentKind

fn clone(&self) -> InstrumentKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InstrumentKind

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

Formats the value using the given formatter.

impl Hash for InstrumentKind

fn hash<__H>(&self, state: &mut __H)where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<InstrumentKind> for InstrumentKind

fn eq(&self, other: &InstrumentKind) -> 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.
