Terse error message on tuple struct looking like regular struct #144595
Description
Code
struct Foo(a: u8, b: u8);Current output
error: expected one of `!`, `(`, `)`, `+`, `,`, `::`, or `<`, found `:`
--> src/lib.rs:4:13
|
4 | struct Foo(a: u8, b: u8)
| ^ expected one of 7 possible tokensDesired output
error: expected one of `!`, `(`, `)`, `+`, `,`, `::`, or `<`, found `:`
--> src/lib.rs:4:13
|
4 | struct Foo(a: u8, b: u8);
| ^ expected one of 7 possible tokens
help: if you wanted to create a tuple struct, remove field names:
--> src/lib.rs:4:13
|
4 ~ struct Foo(a: u8, b: u8);
| --- ---
help: if you wanted to create a regular struct, use curly braces:
--> src/lib.rs:4:13
|
4 - struct Foo(a: u8, b: u8);
4 + struct Foo{a: u8, b: u8}Rationale and extra context
Context: I was writing a quick reproducer, and made this silly grammatical mistake. But the error message completely threw me off
