Types ¶

type Content ¶

type Content struct {
	Text  string // Simple text content
	Parts []Part // Multi-part content
}

Content represents message content - either a string or parts.

func (Content) IsMultiPart ¶

func (c Content) IsMultiPart() bool

IsMultiPart returns true if content has multiple parts.

func (Content) MarshalJSON ¶

func (c Content) MarshalJSON() ([]byte, error)

MarshalJSON serializes Content. Text-only content serializes as a plain string. Multi-part content serializes as an array of typed objects.

func (*Content) UnmarshalJSON ¶

func (c *Content) UnmarshalJSON(data []byte) error

UnmarshalJSON deserializes Content from either a plain string or a typed array.

type ContentType ¶

type ContentType string

ContentType represents the type of content in a message part.

const (
	ContentTypeText       ContentType = "text"
	ContentTypeImage      ContentType = "image"
	ContentTypeFile       ContentType = "file"
	ContentTypeToolCall   ContentType = "tool-call"
	ContentTypeToolResult ContentType = "tool-result"
)

type FilePart ¶

type FilePart struct {
	Data            string         `json:"data,omitempty"`     // base64 encoded (when inline)
	URL             string         `json:"url,omitempty"`      // remote URL (when hosted)
	MimeType        string         `json:"mimeType"`           // e.g., "application/pdf"
	Filename        string         `json:"filename,omitempty"` // optional filename
	ProviderOptions map[string]any `json:"providerOptions,omitempty"`
}

FilePart represents file content. Exactly one of Data or URL should be set: Data carries base64-encoded bytes; URL points to a remote file the provider should fetch (matches ai-sdk's file-url content part and the Anthropic/Gemini url-source variants).

type ImagePart ¶

type ImagePart struct {
	Image           string         `json:"image"`              // base64 or URL
	MimeType        string         `json:"mimeType,omitempty"` // e.g., "image/png"
	ProviderOptions map[string]any `json:"providerOptions,omitempty"`
}

ImagePart represents image content.

type Message ¶

type Message struct {
	Role            Role           `json:"role"`
	Content         Content        `json:"content"`
	ProviderOptions map[string]any `json:"providerOptions,omitempty"`
}

Message represents a single message in a conversation.

func NewAssistantMessage ¶

func NewAssistantMessage(text string) Message

NewAssistantMessage creates an assistant message.

func NewAssistantMessageWithParts ¶

func NewAssistantMessageWithParts(parts ...Part) Message

NewAssistantMessageWithParts creates an assistant message with parts (e.g., tool calls).

func NewSystemMessage ¶

func NewSystemMessage(text string) Message

NewSystemMessage creates a system message.

func NewToolMessage ¶

func NewToolMessage(toolCallID, toolName string, result any, isError bool) Message

NewToolMessage creates a tool result message.

func NewUserMessage ¶

func NewUserMessage(text string) Message

NewUserMessage creates a user message with text.

func NewUserMessageWithParts ¶

func NewUserMessageWithParts(parts ...Part) Message

NewUserMessageWithParts creates a user message with multiple parts.

type Part ¶

type Part interface {
	// contains filtered or unexported methods
}

Part represents a single part of message content.

type ReasoningPart ¶

type ReasoningPart struct {
	Text            string         `json:"text"`
	ProviderOptions map[string]any `json:"providerOptions,omitempty"`
}

ReasoningPart represents reasoning/thinking content from the model. Source: ai-sdk/packages/provider-utils/src/message.ts

type Role ¶

type Role string

Role represents the role of a message sender.

const (
	RoleSystem    Role = "system"
	RoleUser      Role = "user"
	RoleAssistant Role = "assistant"

TextPart represents text content.

	ApprovalID      string         `json:"approvalId"`
	ToolCallID      string         `json:"toolCallId"`
	ToolName        string         `json:"toolName"`
	Input           any            `json:"input"`
	ProviderOptions map[string]any `json:"providerOptions,omitempty"`
}

ToolApprovalRequestPart represents a request for tool execution approval. Source: ai-sdk/packages/provider-utils/src/message.ts

type ToolApprovalResponsePart ¶

type ToolApprovalResponsePart struct {
	ApprovalID       string         `json:"approvalId"`
	Approved         bool           `json:"approved"`
	Reason           string         `json:"reason,omitempty"`
