Implementations

impl RegistryReadGuard

pub fn len(&self) -> usize

Get the number of registered symbols.

pub fn is_empty(&self) -> bool

Whether or not any symbols are present in the registry.

pub fn get(&self, string: &str) -> Option<Symbol>

Check if the registry contains a symbol matching string and return it if so.

This is a simple hash table lookup.

pub fn get_by_address(&self, address: u64) -> Option<Symbol>

Check if a symbol has been registered at address (i.e., it has been produced by Symbol::to_ffi()), and return the symbol if so.

This can be used to verify symbols that have made a round-trip over an FFI boundary.
