Why a flag is a retirement candidate.

Variants

SingleReadSite

The flag has exactly one read site.

TestOnly

Every read site is in a test, story or mock file.

LiteralConstant

The flag is a const bound to a literal and used as a guard.

IdenticalBranches

The guarded branch and the other branch are the same code.

EmptyBranch

No branch of the guard holds code, so the flag does nothing.

GuardsDeadCode

The guarded block holds unused exports.

DefinedNeverRead

The flag is defined, but no code reads it.

FullyRolledOut

The vendor export says the flag is rolled out, or that the flag serves one variation.

ArchivedInVendor

The vendor export says the flag is archived.

MissingInVendor

The code reads the flag, but the vendor export does not hold its key.

VendorOnly

The vendor export holds the flag, but no code reads it.

Implementations

impl RetirementReason
