Tweak suggestions when using incorrect type of enum literal
More accurate suggestions when writing wrong style of enum variant literal:
```
error[E0533]: expected value, found struct variant `E::Empty3`
--> $DIR/empty-struct-braces-expr.rs:18:14
|
LL | let e3 = E::Empty3;
| ^^^^^^^^^ not a value
|
help: you might have meant to create a new value of the struct
|
LL | let e3 = E::Empty3 {};
| ++
```
```
error[E0533]: expected value, found struct variant `E::V`
--> $DIR/struct-literal-variant-in-if.rs:10:13
|
LL | if x == E::V { field } {}
| ^^^^ not a value
|
help: you might have meant to create a new value of the struct
|
LL | if x == (E::V { field }) {}
| + +
```
```
error[E0618]: expected function, found enum variant `Enum::Unit`
--> $DIR/suggestion-highlights.rs:15:5
|
LL | Unit,
| ---- enum variant `Enum::Unit` defined here
...
LL | Enum::Unit();
| ^^^^^^^^^^--
| |
| call expression requires function
|
help: `Enum::Unit` is a unit enum variant, and does not take parentheses to be constructed
|
LL - Enum::Unit();
LL + Enum::Unit;
|
```
```
error[E0599]: no variant or associated item named `tuple` found for enum `Enum` in the current scope
--> $DIR/suggestion-highlights.rs:36:11
|
LL | enum Enum {
| --------- variant or associated item `tuple` not found for this enum
...
LL | Enum::tuple;
| ^^^^^ variant or associated item not found in `Enum`
|
help: there is a variant with a similar name
|
LL | Enum::Tuple(/* i32 */);
| ~~~~~~~~~~~~~~~~;
|
```
Tweak "field not found" suggestion when giving struct literal for tuple struct type:
```
error[E0560]: struct `S` has no field named `x`
--> $DIR/nested-non-tuple-tuple-struct.rs:8:19
|
LL | pub struct S(f32, f32);
| - `S` defined here
...
LL | let _x = (S { x: 1.0, y: 2.0 }, S { x: 3.0, y: 4.0 });
| ^ field does not exist
|
help: `S` is a tuple struct, use the appropriate syntax
|
LL | let _x = (S(/* f32 */, /* f32 */), S { x: 3.0, y: 4.0 });

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrate with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
