Enum FetchOutput 

pub enum FetchOutput {
    Full(FetchResponse),
    Count(CountResponse),
}

One of the two response shapes the fetch tool can produce, depending on count_only.

JsonSchema is implemented manually so the generated schema is rooted at type: "object" with a oneOf of the two variants. The MCP spec requires outputSchema.type == "object", but the default schemars derive for an #[serde(untagged)] enum emits a bare oneOf with no root type, which rmcp’s schema_for_output rejects at startup.

Variants

Full(FetchResponse)

Count(CountResponse)

Trait Implementations

impl Clone for FetchOutput

fn clone(&self) -> FetchOutput

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FetchOutput

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FetchOutput

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for FetchOutput

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Serialize for FetchOutput

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
