Implementations

impl Library

pub fn this_program() -> Result<Self, CString>

pub fn new(filename: &CStr, bind_lazy: bool) -> Result<Self, CString>

pub fn sym_var<'a, T>( &'a self, symbol: &CStr, ) -> Result<LibraryVar<'a, T>, LibraryError>

Returns Ok(None) if symbol’s value is NULL. Returns Err(msg) if dlsym failed with error msg.

pub fn sym_func<'a, F: FnPtr>( &'a self, symbol: &CStr, ) -> Result<LibraryFunc<'a, F>, LibraryError>

F must be a function pointer type

Returns Ok(None) if symbol’s value is NULL. Returns Err(msg) if dlsym failed with error msg.

pub unsafe fn sym_func_unchecked<'a, F>( &'a self, symbol: &CStr, ) -> Result<LibraryFunc<'a, F>, LibraryError>

F must be a function pointer type

Returns Ok(None) if symbol’s value is NULL. Returns Err(msg) if dlsym failed with error msg.

pub fn sym_var_owned<T>( self: &Arc<Self>, symbol: &CStr, ) -> Result<OwnedLibraryVar<T>, LibraryError>

Returns Ok(None) if symbol’s value is NULL. Returns Err(msg) if dlsym failed with error msg.
