Error code E0498
Note: this error code is no longer emitted by the compiler.
The plugin attribute was malformed.
Erroneous code example:
#![feature(plugin)]
#![plugin(foo(args))] // error: invalid argument
#![plugin(bar="test")] // error: invalid argument
The #[plugin] attribute should take a single argument: the name of the plugin.
For example, for the plugin foo:
#![feature(plugin)]
#![plugin(foo)] // ok!
See the plugin feature section of the Unstable book for more details.
