Struct ProfileToken 

pub struct ProfileToken {
    pub id: u64,
    pub opened_on: u64,
}

An open profiling window on a backend, handed out by profile_start and passed back to profile_end to close it.

Windows nest and overlap: a backend keys each on its token.

Fields

id: u64

The backend’s own identifier for the window.

opened_on: u64

The backend’s own identifier for where the window was opened — a stream, a queue — carried so it can be closed there.

Opaque to this crate, and 0 for a backend that has only one such place. A window belongs to where it was opened, not to whoever closes it: the split pair exists for work launched from somewhere else, so the two calls can land on different threads, and a close that guessed from the calling thread would pair a start recorded on one stream with an end recorded on another — which reads as a plausible duration and means nothing.

Trait Implementations

impl Clone for ProfileToken

fn clone(&self) -> ProfileToken

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ProfileToken

impl Debug for ProfileToken

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ProfileToken

fn deserialize<__D>( __deserializer: __D, ) -> Result<ProfileToken, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ProfileToken

impl Hash for ProfileToken

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 for ProfileToken

fn eq(&self, other: &ProfileToken) -> 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 Serialize for ProfileToken

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
