Struct MiddlewareContext 

pub struct MiddlewareContext {
    pub request_id: Option<String>,
    pub trace_id: Option<String>,
    pub parent_span_id: Option<String>,
    pub operation: Option<String>,
}

Structured fields carried across the middleware chain.

Round-trips through serde_json so the bag stays JSON-compatible with the rest of provider_options.

Fields

request_id: Option<String>

Unique id for this end-to-end request.

trace_id: Option<String>

Trace id for distributed tracing (W3C trace-context style).

parent_span_id: Option<String>

Parent span id within the trace.

operation: Option<String>

Logical operation name (e.g. "chat.completion", "embed.query").

Implementations

impl MiddlewareContext

pub fn with_request_id(id: impl Into<String>) -> Self

Build with a fresh request id.

pub fn read(options: &CallOptions) -> Option<Self>

Read the context (if any) from a CallOptions.

Returns None when no llmsdk bucket exists or when its contents don’t deserialize as MiddlewareContext.

pub fn read_from(options: &ProviderOptions) -> Option<Self>

Read from a raw ProviderOptions map.

pub fn write(&self, options: &mut CallOptions)

Write self into a CallOptions, merging onto any existing llmsdk bucket (caller fields win).

Trait Implementations

impl Clone for MiddlewareContext

fn clone(&self) -> MiddlewareContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MiddlewareContext

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

Formats the value using the given formatter.

impl Default for MiddlewareContext

fn default() -> MiddlewareContext

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MiddlewareContext

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MiddlewareContext

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for MiddlewareContext
