Struct Delta 

#[non_exhaustive]
pub struct Delta {
    pub content: Option<String>,
    pub role: Option<String>,
    pub tool_calls: Option<Vec<PartialToolCall>>,

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.

content: Option<String>

role: Option<String>

tool_calls: Option<Vec<PartialToolCall>>

Partial tool call fragments received during streaming.

Each chunk contains only a fragment of the full tool call data. Use ToolAwareStream to accumulate these into complete ToolCall objects.

reasoning: Option<String>

reasoning_details: Option<Vec<ReasoningDetail>>

audio: Option<Value>

refusal: Option<String>
