Enum Severity 

pub enum Severity {
    Error,
    Warning,
    Info,
    Hint,
}

How seriously a diagnostic should be treated by a consumer (CLI renderer, LSP client, editor diagnostics panel).

Until issue #1674, no DiagnosticCode’s default severity (DiagnosticCode::severity) was ever Info or Hint — the two advisory tiers existed only so a project’s [lints] table (brink-project-config’s LintLevel::Info/LintLevel::Hint, resolved through brink_analyzer::effective_severity) could opt a Warning-default code down to one when a squiggle is too loud (issue #1162). Moving any existing code’s default into one of these tiers is a separate decision, deliberately not made by the issue that introduced the tiers. DiagnosticCode::E157 (issue #1674) is the first code to default here directly — RULED “off or info by default” for a narrow, precision-tuned lint that must not nag a single-shot project.

Variants

Error

Blocks compilation / is surfaced as a hard failure.

Warning

Non-fatal; the default tier for advisory diagnostics until a [lints] override says otherwise.

Info

Advisory, LSP DiagnosticSeverity::INFORMATION — worth telling the author about, but not something they need to act on.

Hint

Advisory and quiet, LSP DiagnosticSeverity::HINT — the tier IDEs use for things like unused-symbol dimming, where even an info-level squiggle is too loud.
