Enum CacheScope 

#[non_exhaustive]
pub enum CacheScope {
    Public,
    Private,
}

Scope of a cached result (SEP-2549).

Servers hint to clients how widely they may share a cached tools/list, resources/read, etc. response. The final SEP-2549 wire values are "public" and "private": Public means any client, gateway, or proxy may cache and serve the result across authorization contexts; Private restricts reuse to the same authorization context (a different access token requires a different cache). None on the parent field means the server expresses no opinion.

Earlier drafts of this crate used session/global values that never matched the SEP text; they were replaced before any release advertised 2026-07-28 support.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Public

Any client, gateway, or proxy may cache and serve this result across authorization contexts.

Private

The cached result may only be reused within the same authorization context.
