Scope analysis issue types and analyzer. Category of scope-related issue detected during analysis.

Variants

VariableShadowing

A variable declared in an inner scope shadows one in an outer scope.

UnusedVariable

A declared variable is never read.

UndeclaredVariable

A variable is used without a prior declaration (my/our/local).

VariableRedeclaration

The same variable name is declared twice in the same scope.

DuplicateParameter

A subroutine parameter name appears more than once in the signature.

ParameterShadowsGlobal

A parameter name shadows a package-level (our) variable.

UnusedParameter

A subroutine parameter is never used inside the body.

UnquotedBareword

A bareword was used where a string or identifier was expected.

UninitializedVariable

A variable was accessed before any initializing assignment.

CaptureVarWithoutRegexMatch

Capture variable ($1, $2, etc.) used with no preceding regex match in scope.

Trait Implementations

impl Clone for IssueKind

fn clone(&self) -> IssueKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for IssueKind

impl Debug for IssueKind

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

Formats the value using the given formatter.

impl PartialEq for IssueKind

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