Struct CacheableResult 

pub struct CacheableResult {
    pub ttl_ms: f64,
    pub cache_scope: CacheScope,
}

Core MCP protocol types and error handling Cacheable-result mixin per schema. Embed via #[serde(flatten)]:

pub struct ListToolsResult {
    #[serde(default)]
    pub result_type: crate::result_type::ResultType,

    #[serde(flatten)]
    pub cache: crate::caching::CacheableResult,

    // ... domain-specific fields ...
}

Both fields are REQUIRED on the wire. Constructors should always set them.

Fields

ttl_ms: f64

Cache lifetime hint in milliseconds.

• 0 means immediately stale; client MAY re-fetch every use.
• Positive: client SHOULD consider the result fresh for this many ms.

Schema type is number (@minimum 0) — fractional values are spec-legal and accepted on deserialize; whole values serialize as integers so the common case keeps its compact wire form.

cache_scope: CacheScope

Sharing scope.

Implementations

impl CacheableResult

pub fn new(ttl_ms: f64, cache_scope: CacheScope) -> CacheableResult

Construct with both required fields.

pub fn stale_public() -> CacheableResult

Convenience: immediately-stale public response (ttlMs=0, public scope).

pub fn private_60s() -> CacheableResult

Convenience: 60-second private cache.
