Struct OpenTelemetryContext

pub struct OpenTelemetryContext {
    inner: BTreeMap<String, String>,
}

Available on crate feature tracing only.

An OpenTelemetry context.

Allows associating tracing spans across task or thread boundaries.

Fields

inner: BTreeMap<String, String>

Implementations

impl OpenTelemetryContext

pub fn attach_as_parent(&self)

Attaches this Context to the current tracing span, as its parent.

If there is not enough information in this OpenTelemetryContext to create a context, then the current thread’s Context is used defaulting to the default Context.

pub fn attach_as_parent_to(&self, span: &Span)

Attaches this Context to the given tracing Span, as its parent. as its parent.

If there is not enough information in this OpenTelemetryContext to create a context, then the current thread’s Context is used defaulting to the default Context.

pub fn obtain() -> Self

Obtains a Context from the current tracing span.

pub fn empty() -> Self

Obtains an empty Context.

Trait Implementations

impl Clone for OpenTelemetryContext

fn clone(&self) -> OpenTelemetryContext

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OpenTelemetryContext

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for OpenTelemetryContext

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Extractor for OpenTelemetryContext

fn get(&self, key: &str) -> Option<&str>

Get a value from a key from the underlying data.

fn keys(&self) -> Vec<&str>

Collect all the keys from the underlying data.

impl From<BTreeMap<String, String>> for OpenTelemetryContext

fn from(map: BTreeMap<String, String>) -> Self

Converts to this type from the input type.

impl From<OpenTelemetryContext> for BTreeMap<String, String>

fn from(ctx: OpenTelemetryContext) -> Self

Converts to this type from the input type.

impl Injector for OpenTelemetryContext

fn set(&mut self, key: &str, value: String)

Add a key and value to the underlying data.

impl PartialEq for OpenTelemetryContext

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
