Enum wasmer::ExportError

pub enum ExportError {

}

The ExportError can happen when trying to get a specific export Extern from the Instance exports.

Examples

Incompatible export type

// This results with an error: `ExportError::IncompatibleType`.
let export = instance.exports.get_function("glob").unwrap();

Missing export

// This results with an error: `ExportError::Missing`.
let export = instance.exports.get_function("unknown").unwrap();
