Enum CustomToolInputContentPart 

pub enum CustomToolInputContentPart {
    InputText {
        text: String,
    },
    InputImage {
        detail: Option<Detail>,
        file_id: Option<String>,
        image_url: Option<String>,
    },
    InputFile {
        detail: Option<FileDetail>,
        file_data: Option<String>,
        file_id: Option<String>,
        file_url: Option<String>,
        filename: Option<String>,
    },
}

Input-only content part accepted inside a custom_tool_call_output array.

Spec (openai-responses-api-spec.md L269): the array form of custom_tool_call_output.output permits only ResponseInputText | ResponseInputImage | ResponseInputFile — assistant-facing shapes such as output_text and refusal are explicitly not allowed here. This enum mirrors the three input variants of ResponseContentPart with identical field shapes so spec-compliant payloads round-trip unchanged, while deserialization of output_text/refusal fails loudly instead of being silently coerced.

Other call sites that legitimately carry mixed input/output content parts continue to use ResponseContentPart (Postel-of-liberality preserved for cross-tool reuse).

Variants

InputText

type: "input_text" — inline textual input.

Fields

text: String

InputImage

type: "input_image" — reference to an image supplied by the client. Exactly one of file_id / image_url is typically set; both may be absent when only detail is being conveyed.

Fields

detail: Option<Detail>

file_id: Option<String>

image_url: Option<String>

InputFile

type: "input_file" — reference to an attached file. file_data is a base64 blob; file_url / file_id reference external/uploaded files.

Fields

detail: Option<FileDetail>

file_data: Option<String>

file_id: Option<String>

file_url: Option<String>

filename: Option<String>
