string_commands.go:656–674

SetIFEQ Redis `SET key value [expiration] IFEQ match-value` command. Compare-and-set: only sets the value if the current value equals matchValue. Returns "OK" on success. Returns nil if the operation was aborted due to condition not matching. Zero expiration means the key has no expiration time. N
