Struct DeployerCache 

pub struct DeployerCache { /* private fields */ }

Deployer records keyed by their bytecode meta hash.

The key here is not a digest of the value - a deployer is keyed by its bytecode meta hash while carrying a constructor meta of its own - so the invariant is internal: meta_bytes must hash to meta_hash. A record that gets that wrong describes a deployer whose constructor meta is not the meta it names, and crate::meta::Store copies exactly those bytes into the MetaCache under exactly that hash.

Same shape as MetaCache, for the same reason: the check was a convention spread across call sites, and set_deployer and set_deployer_from_query_response both missed it. rainlanguage/rain.metadata#170.

Implementations

impl DeployerCache

pub fn insert_verified( &mut self, key: &[u8], deployer: NPE2Deployer, ) -> Result<&NPE2Deployer, Error>

Caches deployer under key, and only if its own meta bytes hash to the meta hash it claims for them.

pub fn get(&self, key: &[u8]) -> Option<&NPE2Deployer>

The deployer cached under key, if any.

pub fn contains_key(&self, key: &[u8]) -> bool

Whether anything is cached under key.

pub fn iter(&self) -> impl Iterator<Item = (&Vec<u8>, &NPE2Deployer)>

Every cached pair. Entries are verified by construction.

pub fn is_empty(&self) -> bool

Whether anything is cached at all.

Trait Implementations

impl Clone for DeployerCache

fn clone(&self) -> DeployerCache

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeployerCache

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

Formats the value using the given formatter.

impl Default for DeployerCache

fn default() -> DeployerCache

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DeployerCache

Deserializing is a way in, so it goes through the gate, as for MetaCache.

Deserialize this value from the given Serde deserializer.

impl PartialEq for DeployerCache

fn eq(&self, other: &DeployerCache) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for DeployerCache

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
