Struct CacheRules 

pub struct CacheRules { /* private fields */ }

Whether tables are cached by default, plus include/exclude overrides.

Examples

Cache everything except audit tables:

use valence_backend_hybrid::CacheRules;

let rules = CacheRules::cache_all().exclude(["audit_log"]);
assert!(rules.allows("project"));
assert!(!rules.allows("audit_log"));

Cache only explicit edge tables:

use valence_backend_hybrid::CacheRules;

let rules = CacheRules::cache_none().include(["project_members"]);
assert!(rules.allows("project_members"));
assert!(!rules.allows("other_edge"));

Implementations

impl CacheRules

pub fn cache_all() -> CacheRules

Cache all tables unless listed in Self::exclude.

pub fn cache_none() -> CacheRules

Cache no tables unless listed in Self::include.

pub fn include( self, tables: impl IntoIterator<Item = impl Into<String>>, ) -> CacheRules

Add tables that must be cached (overrides default cache_none).

pub fn exclude( self, tables: impl IntoIterator<Item = impl Into<String>>, ) -> CacheRules

Add tables that must not be cached (overrides default cache_all).

pub fn allows(&self, table: &str) -> bool

Whether table is eligible for caching under these rules.

pub fn validate(&self) -> Result<(), Error>

Validate that include/exclude sets do not contradict each other.

Errors

Returns Error::Internal when the same table appears in both sets.
