A gateable Godot GDScript warning code (research/04 §2.2). Internal to gdscript-hir; the public Diagnostic.code carries its as_str form, so the serialized identity stays a stable string. Adding a variant is a compile error until every table below (as_str, default_level, and ALL) covers it.

Variants

UnassignedVariable

A typed local read before it is assigned.

UnassignedVariableOpAssign

A compound-assign (x += …) on a still-unassigned local.

UnusedVariable

A local var that is never read.

UnusedLocalConstant

A local const that is never read.

UnusedPrivateClassVariable

A _-prefixed class member that is never read in-class.

UnusedParameter

A parameter that is never read (excluding _-prefixed).

UnusedSignal

A signal that is never emitted or connected in-file.

ShadowedVariable

A local that shadows an outer local / parameter.

ShadowedVariableBaseClass

A member that shadows a base-class member.

ShadowedGlobalIdentifier

A class_name / member / local that shadows a global identifier.

UnreachableCode

Statements after an unconditional return/break/continue / an exhaustive match.

UnreachablePattern

A match arm after a wildcard/bind arm.

StandaloneExpression

An expression statement whose value is unused and side-effect-free.

StandaloneTernary

A ternary used as a statement.

IncompatibleTernary

A ternary whose two arms have incompatible types.

UnsafeVoidReturn

return f() where f is Variant into a -> void.

StaticCalledOnInstance

A static method called through an instance.

MissingTool

A base @tool class without a local @tool.

RedundantStaticUnload

@static_unload on a class with no static variables.

RedundantAwait

await on a non-coroutine / non-signal value.

AssertAlwaysTrue

assert(true) / an always-true constant condition.

AssertAlwaysFalse

assert(false) / an always-false constant condition.

IntegerDivision

int / int (the decimal part is discarded).

NarrowingConversion

A float stored into an int slot.

IntAsEnumWithoutCast

An int assigned to an enum without a cast.

IntAsEnumWithoutMatch

An int compared to an enum in a match.

EnumVariableWithoutDefault

var e: SomeEnum with no initializer.

EmptyFile

A file with no members.

DeprecatedKeyword

A deprecated keyword (yield).

ConfusableIdentifier

A mixed-script / homoglyph identifier.

ConfusableLocalDeclaration

A local declared after a same-name outer use.

ConfusableLocalUsage

A use-before-declaration of a local shadowing a member.

ConfusableCaptureReassignment

Reassigning a lambda capture.

ConfusableTemporaryModification

Modifying a temporary (master-only).

PropertyUsedAsFunction

obj.prop() where prop is a property.

ConstantUsedAsFunction

obj.CONST() where CONST is a constant.

FunctionUsedAsProperty

obj.method used as a property.

UntypedDeclaration

var x = … without a : T annotation.

InferredDeclaration

A := inferred declaration.

UnsafePropertyAccess

A property missing on a statically-known base.

UnsafeMethodAccess

A method missing on a statically-known base.

UnsafeCast

An as T through a Variant.

UnsafeCallArgument

An argument needing an unsafe implicit cast into the parameter type.

ReturnValueDiscarded

A non-void call result dropped.

MissingAwait

A await-able call whose result is not awaited (master-only).

InferenceOnVariant

A := / inferred binding from a statically-Variant value.

NativeMethodOverride

Overriding a native virtual with an incompatible signature.

GetNodeDefaultWithoutOnready

A get_node(...) default-value init that should be @onready.

OnreadyWithExport

@onready together with @export on one member.

Implementations

impl WarningCode

pub const ALL: &'static [WarningCode]

Every code, for reverse lookup (from_setting_name) and the W5 docgen. Must list every variant.

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

The stable serialized identity — what Diagnostic.code carries (e.g. INTEGER_DIVISION). These strings are the frozen consumer-facing identifiers (Workstream 6).

pub fn setting_name(self) -> String

The project.godot debug/gdscript/warnings/<tail> key tail — the lowercased [as_str].

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

A one-line human description — the source of truth for the generated Warning Reference (Workstream 5). Kept terse and stable; an exhaustive match so a new code must add one.

pub fn default_level(self) -> WarnLevel

Godot’s default_warning_levels[] entry for this code.

pub fn is_opt_in(self) -> bool

Whether this code is in the opt-in type-strictness group (the codes a standalone/--strict run promotes from IGNORE to WARN). Currently exactly the IGNORE-default set.

pub fn since(self) -> Since

The lowest engine version this code exists in (for version-gating master-only codes).

pub fn from_setting_name(name: &str) -> Option<WarningCode>

The code whose setting_name (case-insensitively) is name, for parsing project.godot keys and @warning_ignore("name") arguments.

Trait Implementations

impl Clone for WarningCode

fn clone(&self) -> WarningCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for WarningCode

impl Debug for WarningCode

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

Formats the value using the given formatter.

impl Eq for WarningCode

impl Hash for WarningCode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for WarningCode

fn eq(&self, other: &WarningCode) -> 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.
