Enum TracingBackend

pub enum TracingBackend {
    Auto,
    Chrome,
    System,
}

Backend type to use for tracing. chrome uses the Chrome-integrated tracing service and is supported on all platforms. system is only supported on Chrome OS and uses the Perfetto system tracing service. auto chooses system when the perfettoConfig provided to Tracing.start specifies at least one non-Chrome data source; otherwise uses chrome.

Trait Implementations

impl AsRef<str> for TracingBackend

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for TracingBackend

fn clone(&self) -> TracingBackend

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TracingBackend

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TracingBackend

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromStr for TracingBackend

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<TracingBackend, <TracingBackend as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for TracingBackend

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 TracingBackend

fn eq(&self, other: &TracingBackend) -> 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 TracingBackend

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.

impl Eq for TracingBackend
