Description
Feature Request
Right now braces are visually inconsistent with parenthesis and brackets.
Rustfmt will do A(a,b) but B { a, b }.
An option to remove the spaces around braces in structs, and blocks would be interesting.
For example
struct Point{x: i64, y: i64}
struct Other(i64, i64)
fn foo(x: i64, y: i64) -> (Point, Other) {
let x = if x < 0 {0} else {x};
(Point{x, y}, Other(x, y))
}
Motivation
This would feel more consistent with other delimiters and would make the inline blocks less unnecessarily spaced out.

Research direction
The issue names no files, tests, or entry points. Start by locating rustfmt's option handling and the formatting logic for struct fields and block expressions, then check existing delimiter-spacing tests. Done means the new option consistently removes brace-adjacent spaces in the examples while preserving current behavior by default.
