Struct ResourceAnnotations 

pub struct ResourceAnnotations {
    pub audience: Option<Vec<ResourceAudience>>,
    pub priority: Option<f32>,
    pub last_modified: Option<String>,
}

MCP Resource 标准 annotations（snake_case mirror）/ MCP standard Resource annotations。

全字段可选（对标 Python ResourceAnnotations(TypedDict, total=False)）。priority 取值 [0, 1] （协议不在类型层强制范围，由生产方保证；边界 0.0 / 1.0 合法）。

Fields

audience: Option<Vec<ResourceAudience>>

目标受众 / intended audience。

priority: Option<f32>

优先级 [0, 1]，越大越重要 / priority in [0, 1], higher = more important。

last_modified: Option<String>

最后修改时间（ISO 8601）/ last-modified timestamp (ISO 8601)。

Trait Implementations

impl Clone for ResourceAnnotations

fn clone(&self) -> ResourceAnnotations

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResourceAnnotations

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

Formats the value using the given formatter.

impl Default for ResourceAnnotations

fn default() -> ResourceAnnotations

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ResourceAnnotations

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ResourceAnnotations

fn eq(&self, other: &ResourceAnnotations) -> 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 ResourceAnnotations

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.
