Support struct expression shorthand field #20830
Description
Fields with the same type and name use the 'shorthand' syntax
Example
struct Foo { bar: bool, n: i32 }
fn baz() {
let bar = true;
let foo: Foo = Fo$0;
}Current:
struct Foo { bar: bool, n: i32 }
fn baz() {
let bar = true;
let foo: Foo = Foo { bar: ${1:()}, n: ${2:()} }$0;
}Expect:
struct Foo { bar: bool, n: i32 }
fn baz() {
let bar = true;
let foo: Foo = Foo { bar$1, n: ${2:()} }$0;
