Enum Severity 

pub enum Severity {
    Error,
    Warning,
    Lint,
}

How loud a diagnostic is. error fails a check; warning and lint do not unless the caller promotes them (htl check --strict, include_tl!).

Variants

Error

The file did not type-check. From the Teal checker, and the only severity that fails a run on its own.

Warning

A kind the Teal compiler reports for itself — an unused local, a redeclaration — which htl surfaces under the rule name of its kind (tl:unused, …) rather than inventing one.

Lint

A finding of one of htl’s own rules. The only severity whose diagnostics carry a rule, because a rule is what a project sets a level for.

Implementations

impl Severity

pub fn as_str(self) -> &'static str

The lowercase word this severity is written as: in the <severity>: a report prints, in --format json, and in the run cache. parse reads it back, so the two are the one spelling that crosses between a run and a replay of it.

pub fn parse(s: &str) -> Option<Self>

The inverse of as_str. None for anything else, which is the answer a reader of stored diagnostics wants: an entry written by a build that knew a fourth severity is refused rather than guessed at.
