Struct brane_tsk::caches::DomainRegistryCache

source · 
pub struct DomainRegistryCache { /* private fields */ }
Expand description

A cache for storing the local registry address of a particular domain.

Implementations§

source§

impl DomainRegistryCache

source

pub fn new(api_address: impl Into<Address>) -> Self

Constructor for the DomainRegistryCache that uses the default timeout.

See DEFAULT_DOMAIN_REGISTRY_CACHE_TIMEOUT to find what the current default is.

§Arguments
  • api_address: The address of a remote centralized brane-api registry that knows an up-to-date mapping of locations to local registries.
§Returns

A new DomainRegistryCache instance.

source

pub fn with_timeout( timeout: impl AsPrimitive<u64>, api_address: impl Into<Address>, ) -> Self

Constructor for the DomainRegistryCache.

§Arguments
  • timeout: A timeout (in seconds) that determines after how long entries in the cache become stale.
  • api_address: The address of a remote centralized brane-api registry that knows an up-to-date mapping of locations to local registries.
§Returns

A new DomainRegistryCache instance.

source

pub async fn get<'s>( &'s self, location: &Location, ) -> Result<Address, DomainRegistryCacheError>

Resolves a given location identifier to an address.

If we know the mapping already (and it isn’t stale), then the in-memory cached address is returned.

Else, a query is made to the API address that is given in this type’s constructor.

§Arguments
  • location: The Location ID to search for.
§Returns

A reference to the address of the location.

§Errors

This function may error if we had to retrieve the address from the remote registry but failed.
