Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

reasoning_details: Option<Option<Vec<ReasoningDetail>>>

reasoning_content: Option<Option<String>>

Plain-text reasoning returned by compatible providers (for example DeepSeek).

reasoning: Option<Option<String>>

Alternative compatible-provider spelling. Kept separately on the wire.

role: Option<Option<DeltaRole>>

content: Option<Option<String>>

refusal: Option<Option<String>>

function_call: Option<Option<DeltaFunctionCall>>

tool_calls: Option<Option<Vec<DeltaToolCall>>>

rest: Rest
