Enum wasmer_engine::InstantiationError

pub enum InstantiationError {
    Link(LinkError),
    Start(RuntimeError),
}

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.

Start(RuntimeError)

A runtime error occured while invoking the start function

Trait Implementations

impl Debug for InstantiationError

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

Formats the value using the given formatter.

impl Display for InstantiationError

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

Formats the value using the given formatter.

impl Error for InstantiationError

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

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
