Enum PCallError 

#[repr(i32)]
pub enum PCallError {
    RuntimeError = 2,
    MemoryError = 4,
    ErrorHandlerError = 5,
}

All error codes that a function may return when erroring while called in protected mode.

This enum is used by the following functions:

• LuaState::pcall.
• LuaState::cpcall.

Variants

RuntimeError = 2

Any error during runtime.

MemoryError = 4

Memory allocation error (rare).

(LuaState::pcall will not call the error handler for these errors.)

ErrorHandlerError = 5

Error while calling the error handler.

Implementations

impl PCallError

pub const unsafe fn check_raw(value: i32) -> Result<(), Self>

Converts the given value into a Result.

Safety

value must either be 0 or a valid PCallError value.

Errors

Returns Err if value is not 0.

Trait Implementations

impl Debug for PCallError

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

Formats the value using the given formatter.

impl Display for PCallError

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

Formats the value using the given formatter.

impl Error for PCallError

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

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

Provides type-based access to context intended for error reports.
