I get an assertion failure while trying to compile the following
use io::println;
fn main() {
trait Text {
fn to_str(&self) -> ~str;
}
fn to_string(t: Text) {
println(t.to_str());
}
}
amitava:l2 amitava$ rustc -g trait.rs
Assertion failed: (Ty && "Invalid GetElementPtrInst indices for type!"),
function checkGEPType, file
/Users/amitava/opt/rust/src/rust/src/llvm/include/llvm/Instructions.h, line
705.
Abort trap: 6
Clearly, this code is nonsensical since there is no implementation of the
trait "Text". Should the compiler produce a different message?
Thanks & Regards,
Amitava Shee
There are two ways of constructing a software design. One is to make it so
simple that there are obviously no deficiencies; the other is to make it so
complicated that there are no obvious deficiencies. The first method is far
more difficult.
