Struct NumberSchema 

#[non_exhaustive]
pub struct NumberSchema {
    pub type_: NumberTypeConst,
    pub title: Option<Cow<'static, str>>,
    pub description: Option<Cow<'static, str>>,
    pub minimum: Option<f64>,
    pub maximum: Option<f64>,
    pub default: Option<f64>,
}

Schema definition for number properties (floating-point).

Compliant with MCP 2025-06-18 specification for elicitation schemas. Supports only the fields allowed by the MCP spec.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

type_: NumberTypeConst

Type discriminator

title: Option<Cow<'static, str>>

Optional title for the schema

description: Option<Cow<'static, str>>

Human-readable description

minimum: Option<f64>

Minimum value (inclusive)

maximum: Option<f64>

Maximum value (inclusive)

default: Option<f64>

Default value

Trait Implementations

impl Clone for NumberSchema

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NumberSchema

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

Formats the value using the given formatter.

impl Default for NumberSchema

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for NumberSchema

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for NumberSchema

Available on crate feature schemars only.

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 NumberSchema

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for NumberSchema

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

where __S: Serializer,
