Struct mun_runtime::InvokeErr3

pub struct InvokeErr3<'s, A: ArgumentReflection, B: ArgumentReflection, C: ArgumentReflection, Output: ReturnTypeReflection> { /* fields omitted */ }

An invocation error that contains the function name, a mutable reference to the runtime, passed arguments, and the output type. This allows the caller to retry the function invocation using the Retriable trait.

Implementations

impl<'s, A: ArgumentReflection, B: ArgumentReflection, C: ArgumentReflection, Output: ReturnTypeReflection> InvokeErr3<'s, A, B, C, Output>

pub fn new(
    err_msg: String,
    runtime: Rc<RefCell<Runtime>>,
    function_name: &'s str,
    a: A,
    b: B,
    c: C
) -> Self

Constructs a new invocation error.

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

Formats the value using the given formatter.

impl<'s, A: ArgumentReflection, B: ArgumentReflection, C: ArgumentReflection, Output: ReturnTypeReflection> Display for InvokeErr3<'s, A, B, C, Output>

impl<'s, A: ArgumentReflection, B: ArgumentReflection, C: ArgumentReflection, Output: ReturnTypeReflection> Error for InvokeErr3<'s, A, B, C, Output>

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.

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 Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
