Struct SignatureCache 

pub struct SignatureCache { /* private fields */ }

Signature cache manager

Implementations

impl SignatureCache

pub fn new() -> Self

Create a new cache with default path (~/.cache/ethcli/signatures.json)

pub fn with_path(path: PathBuf) -> Self

Create a cache with a custom path

pub fn default_cache_path() -> PathBuf

Get the default cache directory path

pub fn save(&self)

Force save cache to file immediately

pub fn get_event(&self, topic0: &str) -> Option<String>

Get event signature by topic0 hash

pub fn set_event(&self, topic0: &str, signature: &str)

Set event signature

pub fn get_function(&self, selector: &str) -> Option<String>

Get function signature by 4-byte selector

pub fn set_function(&self, selector: &str, signature: &str)

Set function signature

pub fn set_events_batch(&self, entries: &[(String, String)])

Batch set multiple event signatures

pub fn set_functions_batch(&self, entries: &[(String, String)])

Batch set multiple function signatures

pub fn is_not_found(&self, key: &str) -> bool

Check if a key is in the negative cache (recently looked up but not found)

Returns true if we should skip looking this up again

pub fn set_not_found(&self, key: &str)

Mark a key as not found (for negative caching)

pub fn clear_not_found(&self, key: &str)

Remove a key from the negative cache (when it’s been found elsewhere)

pub fn get_abi( &self, chain_id: u64, address: &str, ) -> Option<(String, Option<String>)>

Get cached ABI for a contract

pub fn set_abi( &self, chain_id: u64, address: &str, abi: &str, name: Option<&str>, )

Cache an ABI for a contract

pub fn abi_count(&self) -> usize

Get number of cached ABIs

pub fn find_function_in_abis(&self, selector: &[u8; 4]) -> Option<String>

Search all cached ABIs for a function matching the given selector

Returns the function signature string if found (e.g., “transfer(address,uint256)”)

pub fn find_event_in_abis(&self, topic0: &[u8; 32]) -> Option<String>

Search all cached ABIs for an event matching the given topic0

Returns the event signature string if found (e.g., “Transfer(address,address,uint256)”)

pub fn stats(&self) -> CacheStats

Get cache statistics

pub fn cleanup(&self)

Clear expired entries

pub fn clear(&self)

Clear all cached data

Trait Implementations

impl Default for SignatureCache

fn default() -> Self

Returns the “default value” for a type.

impl Drop for SignatureCache

fn drop(&mut self)

Executes the destructor for this type.
