Struct McpCacheHint 

pub struct McpCacheHint {
    pub ttl_ms: Option<u64>,
    pub scope: Option<&'static str>,
}

Conservative cache hint surfaced on RC results. Servers can override the defaults per handler when they have a better answer; clients fall back to the constants in DEFAULT_LIST_CACHE_TTL_MS.

Fields

ttl_ms: Option<u64>

scope: Option<&'static str>

Implementations

impl McpCacheHint

pub const fn list_default() -> Self

pub const fn read_default() -> Self

pub const fn none() -> Self

pub fn from_result(result: &JsonValue) -> Option<Self>

Extract a cache hint from an RC result body. Returns None when neither ttlMs nor a recognized cacheScope is present; unknown scopes are silently dropped so we stay forward-compatible.

pub fn to_json_object(&self) -> Map<String, JsonValue>

Trait Implementations

impl Clone for McpCacheHint

fn clone(&self) -> McpCacheHint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for McpCacheHint

impl Debug for McpCacheHint

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

impl Eq for McpCacheHint

impl PartialEq for McpCacheHint

fn eq(&self, other: &McpCacheHint) -> 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.
