Description
I was playing around with some simple code and after making a mistake (typo) and trying to compile it I a got some "semi-ambiguous" error message. The first part helped me to identify the issue while the second part did confused me a bit.
struct Person {
age: uint,
phone:uint,
}
fn main(){
let fernando = Person {age:29, phone:456};
let age = {
let Person {age: ref my_age, age: _} = fernando;
my_age
};
println!("{}",age);
}test.rs:15:9: 15:41 error: field `age` bound twice in pattern
test.rs:15 let Person {age: ref my_age, age: _} = fernando;
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
test.rs:15:9: 15:41 error: pattern does not mention field `phone`
test.rs:15 let Person {age: ref my_age, age: _} = fernando;
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
error: internal compiler error: no type for node 32: pat _ (id=32) in fcx 0x113daad28
note: the compiler hit an unexpected failure path. this is a bug.
note: we would appreciate a bug report: http://doc.rust-lang.org/complement-bugreport.html
note: run with `RUST_BACKTRACE=1` for a backtrace
task 'rustc' failed at 'Box<Any>', /Users/rustbuild/src/rust-buildbot/slave/nightly-mac/build/src/libsyntax/diagnostic.rs:163
I ran this thru several folks at the rust IRC and they suggested the report.
