Enum Turn 

#[non_exhaustive]
pub enum Turn {
    User {
        content: Vec<ContentPart>,
    },
    Assistant {
        content: Vec<ContentPart>,
        tools: Vec<ToolPair>,
    },
}

One turn in a compacted conversation. Sealed so a Turn::Assistant can only carry ToolPairs constructed via the compactor’s internal grouping code (paired calls + results).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

User

User-authored message — opaque content, never paired.

Fields

content: Vec<ContentPart>

Multi-part content (text, image, …).

Assistant

Assistant-authored message + the tool round-trips it initiated. Empty tools means the assistant turn produced final text only.

Fields

content: Vec<ContentPart>

Assistant’s content (may include ContentPart::ToolUse blocks; the embedded tool-use ids match the corresponding ToolPair::ids).

tools: Vec<ToolPair>

Matched tool round-trips initiated by this turn.
