Enum GlobalError

pub enum GlobalError {
    ImmutableGlobalCannotBeSet,
    IncorrectType {
        expected: Type,
        found: Type,
    },
}

Error type describing things that can go wrong when operating on Wasm Globals.

Variants

ImmutableGlobalCannotBeSet

The error returned when attempting to set an immutable global.

IncorrectType

The error returned when attempting to operate on a global as a specific type that differs from the global’s own type.

Fields

expected: Type

The type that the global is.

found: Type

The type that we were asked to use it as.

Trait Implementations

impl Clone for GlobalError

fn clone(&self) -> GlobalError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GlobalError

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

Formats the value using the given formatter.

impl Display for GlobalError

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

Formats the value using the given formatter.

impl Error for GlobalError

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>)

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

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

impl Hash for GlobalError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for GlobalError

fn eq(&self, other: &GlobalError) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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