Enum dlopen::Error

pub enum Error {
    NullCharacter(NulError),
    OpeningLibraryError(IoError),
    SymbolGettingError(IoError),
    NullSymbol,
    AddrNotMatchingDll(IoError),
}

This is a library-specific error that is returned by all calls to all APIs.

Variants

NullCharacter(NulError)

Provided string could not be coverted into std::ffi::CString because it contained null character.

OpeningLibraryError(IoError)

NullSymbol

Value of the symbol was null.

AddrNotMatchingDll(IoError)

impl Error for Error

fn description(&self) -> &str

Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn ErrorTrait>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

impl From<NulError> for Error

fn from(val: NulError) -> Error

Performs the conversion.
