Struct FormatViolation 

pub struct FormatViolation {
    pub line: usize,
    pub col: usize,
    pub rule: &'static str,
    pub message: String,
    pub before: Option<String>,
    pub after: Option<String>,
}

One formatter rule firing on one location. Emitted by try_format_source alongside the rewritten text, then folded into a canonical needs-format Diagnostic by the factory.

rule is a stable slug (“bad-operator-spacing”, “effect-order”, “verify-block-order”, …) consumed by LSP code, docs, and CI rules. before/after are optional short snippets for teaching; long rewrites can omit them.

Fields

line: usize

col: usize

rule: &'static str

message: String

before: Option<String>

after: Option<String>
