Enum budvm::Error

pub enum Error<'a, Env, ReturnType>where
    Env: Environment,{
    Link(LinkError),
    Fault(Fault<'a, Env, ReturnType>),
}

All errors that can be encountered executing Bud code.

Variants

Link(LinkError)

An error occurred while linking an Module.

Fault(Fault<'a, Env, ReturnType>)

A fault occurred while running the virtual machine.

Implementations

impl<'a, Env, ReturnType> Error<'a, Env, ReturnType>where Env: Environment,

pub fn expect_no_pause(self) -> Error<'static, Env, ReturnType>

Asserts that this error does not contain a paused execution. Returns an Error instance with a 'static lifetime.

Panics

If this contains Error::Fault with a kind of FaultOrPause::Pause, this function will panic. Paused execution mutably borrows the virtual machine’s state.

Trait Implementations

impl<Env, ReturnType> Clone for Error<'static, Env, ReturnType>where Env: Environment,

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a, Env, ReturnType: Debug> Debug for Error<'a, Env, ReturnType>where Env: Environment + Debug,

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

Formats the value using the given formatter.

impl<'a, Env, ReturnType> Display for Error<'a, Env, ReturnType>where Env: Environment,

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

Formats the value using the given formatter.

impl<'a, Env, ReturnType> Error for Error<'a, Env, ReturnType>where Env: Debug + Environment, ReturnType: Debug,

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

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, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

impl<'a, Env, ReturnType> From<Fault<'a, Env, ReturnType>> for Error<'a, Env, ReturnType>where Env: Environment,

fn from(fault: Fault<'a, Env, ReturnType>) -> Self

Converts to this type from the input type.

impl<'a, Env, ReturnType> From<FaultKind> for Error<'a, Env, ReturnType>where Env: Environment,

fn from(fault: FaultKind) -> Self

Converts to this type from the input type.

impl<'a, Env, ReturnType> From<LinkError> for Error<'a, Env, ReturnType>where Env: Environment,

fn from(err: LinkError) -> Self

Converts to this type from the input type.

impl<'a, Env, ReturnType: PartialEq> PartialEq<Error<'a, Env, ReturnType>> for Error<'a, Env, ReturnType>where Env: Environment + PartialEq,

fn eq(&self, other: &Error<'a, Env, ReturnType>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
