Enum DiagnosticLayer 

pub enum DiagnosticLayer {
    Lexical,
    Structural,
    Semantic,
    Warning,
    OperationalMaterialization,
    Meta,
}

The layer a diagnostic belongs to — the first axis of the T13 comparison method (docs/zic-warning-parity.md). Recorded as a machine-checkable accessor so the taxonomy cannot silently drift from the doc.

Variants

Lexical

The byte/line stream is not well-formed zic text (NUL, overlong, unknown keyword, field count).

Structural

Lines are well-formed but don’t assemble into a valid record graph (continuation/duplicate/…).

Semantic

A field/value is individually invalid or unrepresentable (month, day-rule, time, value, …).

Warning

Accepted, but a portability/obsolescence/client-compat hazard (-v-style warnings).

OperationalMaterialization

Caused by output materialization, not the source text (path traversal, no-clobber, mode, alias-map validation). A diagnostic, but not a source zic -v diagnostic (T13.5).

Meta

Tool-level / oracle meta (e.g. a compare mismatch), not a source diagnostic.

Trait Implementations

impl Clone for DiagnosticLayer

fn clone(&self) -> DiagnosticLayer

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for DiagnosticLayer

impl Debug for DiagnosticLayer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for DiagnosticLayer

impl PartialEq for DiagnosticLayer

fn eq(&self, other: &DiagnosticLayer) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
