Enum PrimitiveSchema 

pub enum PrimitiveSchema {
    Enum(EnumSchema),
    String(StringSchema),
    Number(NumberSchema),
    Integer(IntegerSchema),
    Boolean(BooleanSchema),
}

Primitive schema definition for elicitation properties.

According to MCP 2025-06-18 specification, elicitation schemas must have properties of primitive types only (string, number, integer, boolean, enum).

Note: Put Enum as the first variant to avoid ambiguity during deserialization. This is due to the fact that EnumSchema can contain StringSchema internally and serde uses first match wins strategy when deserializing untagged enums.

Variants

Enum(EnumSchema)

Enum property (explicit enum schema)

String(StringSchema)

String property (with optional enum constraint)

Number(NumberSchema)

Number property (with optional enum constraint)

Integer(IntegerSchema)

Integer property (with optional enum constraint)

Boolean(BooleanSchema)

Boolean property

Trait Implementations

impl Clone for PrimitiveSchema

fn clone(&self) -> PrimitiveSchema

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrimitiveSchema

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PrimitiveSchema

fn deserialize<__D>( __deserializer: __D, ) -> Result<PrimitiveSchema, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for PrimitiveSchema

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 PartialEq for PrimitiveSchema

fn eq(&self, other: &PrimitiveSchema) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for PrimitiveSchema

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
