As Aatch mentioned, this isn't currently possible. A workaround is to use a dummy parameter to specify the type of Self
:
pub trait TypeTrait {
fn type_id(_: Option<Self>) -> u16;
}
pub struct CustomType {
// fields...
}
impl TypeTrait for CustomType {
fn type_id(_: Option<CustomType>) -> u16 { 0 }
}
pub fn get_type_id<T : TypeTrait>() {
let type_id = TypeTrait::type_id(None::<T>);
}
