Error code E0535

An unknown argument was given to the inline attribute.

Erroneous code example:

#[inline(unknown)] // error: invalid argument
pub fn something() {}

fn main() {}

The inline attribute only supports two arguments:

• always
• never

All other arguments given to the inline attribute will return this error. Example:

#[inline(never)] // ok!
pub fn something() {}

fn main() {}
