Enum Content 

#[non_exhaustive]
pub enum Content {
    Text(String),
    ToolUse(ToolCall),
    ToolResult(ToolResult),
    Image(ImageRef),
}

A single content block within a Message.

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.

Text(String)

Plain text.

ToolUse(ToolCall)

A tool invocation emitted by the model.

ToolResult(ToolResult)

The result of a prior Content::ToolUse, fed back to the model.

Image(ImageRef)

A reference to an image (HTTP URL or data: URI).

Implementations

impl Content

pub fn text(s: impl Into<String>) -> Self

Wraps s in a Content::Text variant.

pub fn tool_use( id: impl Into<String>, name: impl Into<String>, args_json: impl Into<String>, ) -> Self

Constructs a Content::ToolUse block.

pub fn tool_use_signed( id: impl Into<String>, name: impl Into<String>, args_json: impl Into<String>, signature: Option<String>, ) -> Self

Constructs a Content::ToolUse block carrying an opaque provider-specific signature (e.g. a thinking model’s thought signature, which some providers require echoed back on the next request that includes this call).

pub fn tool_result( tool_call_id: impl Into<String>, result_json: impl Into<String>, is_error: bool, ) -> Self

Constructs a Content::ToolResult block.

pub fn image(url: impl Into<String>, mime_type: Option<String>) -> Self

Constructs a Content::Image block.
