Enum AzureStreamEvent 

pub(crate) enum AzureStreamEvent {
    ResponseCreated,
    ResponseCompleted,
    OutputItemAdded,
    OutputItemDone,
    FunctionCallArgumentsDelta,
    CustomToolCallInputDelta,
    OutputTextDelta,
    RefusalDelta,
    Incomplete,
    ErrorReported,
    Other,
}

One Azure SSE event name, classified once instead of by a separate &str match in each parser that reacts to it.

The three parsers deliberately disagree about the same event — OutputTextDelta is a hard error in the tool-call parser, the classification signal here, and ordinary traffic in the text parser — so this only says what the event is, never what to do about it. Each parser still matches its own subset of variants and keeps a catch-all for the rest, including Self::Other.

Variants

ResponseCreated

ResponseCompleted

OutputItemAdded

OutputItemDone

FunctionCallArgumentsDelta

CustomToolCallInputDelta

OutputTextDelta

RefusalDelta

Incomplete

ErrorReported

Other

Anything not matched by name above, including traffic every parser is fine to ignore (response.in_progress, reasoning summaries, …) and names outside ALL_EXPECTED_EVENTS.

Implementations

impl AzureStreamEvent

pub(crate) fn from_wire(name: &str) -> Self

pub(crate) fn of_data_line( preceding_event: Option<Self>, response_type: Option<&str>, ) -> Option<Self>

Which event a data: line belongs to: the event: line that preceded it, or, when none did, the line’s own type field.

The one rule all three readers of the stream use, so the same line cannot count as, say, Azure’s finished copy of an item for one reader and its added copy for another. type is only a fallback because it is optional on the wire.

fn for_event_line(name: &str) -> Self

Classifies an event: line, warning once if the name falls outside everything a parser reacts to and ALL_EXPECTED_EVENTS.

Trait Implementations

impl Clone for AzureStreamEvent

fn clone(&self) -> AzureStreamEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AzureStreamEvent

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

Formats the value using the given formatter.

impl PartialEq for AzureStreamEvent

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