Enum ResourceBody 

pub enum ResourceBody {
    Json(Value),
    Text {
        mime_type: String,
        content: String,
    },
}

The payload of a resource read, carrying both MIME type and serialized content. Different resources speak different formats (JSON for metadata, markdown for human overviews, CSV for spreadsheet consumers), so the resource layer needs to pass both along to the MCP client.

Json variants are pretty-printed when rendered; Text variants are emitted verbatim. Tests and prompt helpers can still access the underlying JSON via ResourceBody::as_json when it’s a JSON payload.

Variants

Json(Value)

Structured JSON — rendered as pretty-printed application/json.

Text

Free-form text with an explicit MIME type (e.g. text/markdown, text/csv).

Fields

mime_type: String

IANA media type, e.g. text/markdown or text/csv.

content: String

The literal text to return to the client, verbatim.

Implementations

impl ResourceBody

pub fn mime_type(&self) -> &str

Return the MIME type this body will be served with.

pub fn to_text(&self) -> String

Render the body to the text payload the client will receive. JSON variants are pretty-printed; text variants return as-is.

pub fn as_json(&self) -> Option<&Value>

Borrow the underlying Value when this body is JSON. Useful for tests that want to assert on individual fields without reparsing.

Trait Implementations

impl Clone for ResourceBody

fn clone(&self) -> ResourceBody

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResourceBody

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

Formats the value using the given formatter.
