Enum ContentBlock 

pub enum ContentBlock {
    Text {
        text: String,
    },
    Image {
        attachment_id: String,
    },
    Audio {
        attachment_id: String,
    },
    Video {
        attachment_id: String,
    },
    ToolUse {
        tool_call_id: ToolCallId,
        name: String,
        input: Value,
    },
    ToolResult {
        tool_call_id: ToolCallId,
        content: Vec<ContentBlock>,
    },
    Unknown,
}

Re-exports of the v2 wire types per ADR 0015. v2 is shipped as part of inferd-client 0.2 so consumers building against v2 can reach the proto types without a separate inferd-proto dep. One element of a MessageV2::content array.

Forward-compatibility: unknown content-block types deserialise as the Unknown variant so v2.0 daemons / clients ignore content shapes added in later v2.x revisions gracefully. The daemon emits invalid_request only if the model needs the unknown content to proceed (per ADR 0015 §“v2 ContentBlock variants”).

Variants

Text

Plain text segment within a message.

Fields

text: String

Inline text. May be empty (rare but legal).

Image

Reference to an image-kind attachment in the request’s top-level attachments[] table.

Fields

attachment_id: String

Must match exactly one Attachment::id of kind Image.

Audio

Reference to an audio-kind attachment.

Fields

attachment_id: String

Must match exactly one Attachment::id of kind Audio.

Video

Reference to a video-kind attachment. Backends that don’t support video reject the request with attachment_unsupported.

Fields

attachment_id: String

Must match exactly one Attachment::id of kind Video.

ToolUse

Assistant-emitted invocation. Consumers don’t typically construct these on the request side — the daemon emits them as response frames; consumers then send a follow-up request with a matching ToolResult block. Allowed in request messages[] only when replaying prior assistant turns for context.

Fields

tool_call_id: ToolCallId

Pairs this invocation with the corresponding ToolResult.

name: String

Tool name, must match a Tool::name from the request’s tools[] table (or a tool the model knows from training).

input: Value

JSON arguments emitted by the model.

ToolResult

Consumer-constructed result of executing a tool. Routed back into the model’s context by the daemon’s chat-templating layer.

Fields

tool_call_id: ToolCallId

Must match the tool_call_id of the assistant-emitted ToolUse block this is responding to.

content: Vec<ContentBlock>

Result content; typically a single Text block.

Unknown

Forward-compatible escape hatch — any type value the local build doesn’t recognise lands here so older clients/daemons don’t reject newer payloads at parse time.

Trait Implementations

impl Clone for ContentBlock

fn clone(&self) -> ContentBlock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContentBlock

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ContentBlock

fn deserialize<__D>( __deserializer: __D, ) -> Result<ContentBlock, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ContentBlock

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
