Enum InstantiationError

pub enum InstantiationError {
    Link(LinkError),
    CpuFeature(String),
    Start(Trap),
}

An error while instantiating a module.

This is not a common WebAssembly error, however we need to differentiate from a LinkError (an error that happens while linking, on instantiation) and a Trap that occurs when calling the WebAssembly module start function.

Variants

Link(LinkError)

A linking ocurred during instantiation.

CpuFeature(String)

The module was compiled with a CPU feature that is not available on the current host.

Start(Trap)

Available on non-WebAssembly only.

A runtime error occured while invoking the start function

Trait Implementations

impl Debug for InstantiationError

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

Formats the value using the given formatter.

impl Display for InstantiationError

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

Formats the value using the given formatter.

impl Error for InstantiationError

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.
