Struct MessageAlternative 

pub struct MessageAlternative {
    pub content: String,
    pub images: Vec<ImageRef>,
    pub content_blocks: Vec<ContentBlock>,
    pub timestamp: String,
    pub provider_key: Option<String>,
}

Stored alternate body for a regenerated assistant message.

Message keeps the currently selected alternative in its top-level content/content_blocks fields so existing clients and prompt assembly keep reading the active response. alternatives stores every selectable candidate, including the active one.

Fields

content: String

images: Vec<ImageRef>

content_blocks: Vec<ContentBlock>

timestamp: String

provider_key: Option<String>

Provider key that minted this alternative’s content. A regenerated assistant body can be produced under a different provider than the original message or a sibling alternative, so each alternative carries its own provenance rather than inheriting the single Message::provider_key. The replay portability filter uses this to drop opaque thinking data the active provider cannot interpret. None for alternatives persisted before per-alternative provenance tracking, in which case callers fall back to Message::provider_key.

Implementations

impl MessageAlternative

pub fn normalize(&mut self)

Ensure content and content_blocks are consistent after deserialization, matching Message::normalize.

Trait Implementations

impl Clone for MessageAlternative

fn clone(&self) -> MessageAlternative

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MessageAlternative

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MessageAlternative

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MessageAlternative

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
