E.g., an interval referring to \"hello\" in \"hello world\"\n * should have a start position of 0 and an end position of 5.\n *\n * To see why, consider what happens if \"llo wor\" is removed from the string to make \"held\".\n * The interval's startpoint remains on the \"h\" (it isn't altered), but the interval's endpoint\n * slides forward to the next unremoved position, which is the \"l\" in \"held\".\n * Users would generally expect the interval to now refer to \"he\" (as it is the subset of content\n * remaining after the removal), hence the \"l\" should be excluded.\n * If the interval endpoint was treated inclusively, the interval would now refer to \"hel\", which\n * is undesirable.\n *\n * Since the endpoints of an interval are treated exclusively but cannot be greater\n * than

E.g., an interval referring to \"hello\" in \"hello world\"\n * should have a start position of 0 and an end position of 5.\n *\n * To see why, consider what happens if \"llo wor\" is removed from the string to make \"held\".\n * The interval's startpoint remains on the \"h\" (it isn't altered), but the interval's endpoint\n * slides forward to the next unremoved position, which is the \"l\" in \"held\".\n * Users would generally expect the interval to now refer to \"he\" (as it is the subset of content\n * remaining after the removal), hence the \"l\" should be excluded.\n * If the interval endpoint was treated inclusively, the interval would now refer to \"hel\", which\n * is undesirable.\n *\n * Since the endpoints of an interval are treated exclusively but cannot be greater\n * than or equal to the length of the associated sequence, there exist special\n * endpoint segments, \"start\" and \"end\", which represent the position immediately\n * before or immediately after the string respectively.\n *\n * If a `SequenceInterval` is created on a sequence with the\n * `mergeTreeReferencesCanSlideToEndpoint` feature flag set to true, the endpoints\n * of the interval that are exclusive will have the ability to slide to these\n * special endpoint segments.\n * @alpha\n * @legacy\n */\nexport interface SequenceInterval extends ISerializableInterval {\n\treadonly start:
