/*
 * General rule strategy:
 * 1. An OffsetStorage instance stores a map of desired offsets, where each token has a specified offset from another
 *    specified token or to the first column.
 * 2. As the AST is traversed, modify the desired offsets of tokens accordingly. For example, when entering a
 *    BlockStatement, offset all of the tokens in the BlockStatement by 1 indent level from the opening curly
 *    brace of the BlockStatement.
 * 3. After traversing the AST, calculate the expected indentation levels of every token according to the
 *    OffsetStorage container.
 * 4. For each line, compare the expected indentation of the first token to the actual indentation in the file,
 *    and report the token if the two values are not equal.

/**
	 * Sets the desired offset of a token.
	 *
	 * This uses a line-based offset collapsing behavior to handle tokens on the same line.
	 * For example, consider the following two cases:
	 *
	 * (
	 *     [
	 *         bar
	 *     ]
	 * )
	 *
	 * ([
	 *     bar
	 * ])
	 *
	 * Based on the first case, it's clear that the `bar` token needs to have an offset of 1 indent level (4 spaces) from
	 * the `[` token, and the `[` token has to have an offset of 1 indent level from the `(` token. Since the `(` token is
	 * the first on its line (with an indent of 0 spaces), the `bar` token needs to be offset by 2 indent levels (8 spaces)
	 * from the start of its line.
	 *
	 * However, in the second case `bar` should only be indented by 4 spaces. This is because the offset of 1 indent level
	 * between the `(` and the `[` tokens gets "collapsed" because the two tokens are on the same line. As a result, the
	 * `(` token is mapped to the `[` token with an offset of 0, and the rule correctly decides that `bar` should be indented
	 * by 1 indent level from the start of the line.
	 *
	 * This is useful because rule listeners can usually just call `setDesiredOffset` for all the tokens in the node,
	 * without needing to check which lines those tokens are on.
	 *
	 * Note that since collapsing only occurs when two tokens are on the same line, there are a few cases where non-intuitive
	 * behavior can occur. For example, consider the following cases:
	 *
	 * foo(
	 * ).
	 *     bar(
	 *         baz
	 *     )
	 *
	 * foo(
	 * ).bar(
	 *     baz
	 * )
	 *
	 * Based on the first example, it would seem that `bar` should be offset by 1 indent level from `foo`, and `baz`
	 * should be offset by 1 indent level from `bar`. However, this is not correct, because it would result in `baz`
	 * being indented by 2 indent levels in the second case (since `foo`, `bar`, and `baz` are all on separate lines, no
	 * collapsing would occur).
	 *
	 * Instead, the correct way would be to offset `baz` by 1 level from `bar`, offset `bar` by 1 level from the `)`, and
	 * offset the `)` by 0 levels from `foo`. This ensures that the offset between `bar` and the `)` are correctly collapsed
	 * in the second case.
	 * @param {Token} token The token
	 * @param {Token} fromToken The token that `token` should be offset from
	 * @param {number} offset The desired indent level
	 * @returns {void}

/**
	 * Sets the desired offset of all tokens in a range
	 * It's common for node listeners in this file to need to apply the same offset to a large, contiguous range of tokens.
	 * Moreover, the offset of any given token is usually updated multiple times (roughly once for each node that contains
	 * it). This means that the offset of each token is updated O(AST depth) times.
	 * It would not be performant to store and update the offsets for each token independently, because the rule would end
	 * up having a time complexity of O(number of tokens * AST depth), which is quite slow for large files.
	 *
	 * Instead, the offset tree is represented as a collection of contiguous offset ranges in a file. For example, the following
	 * list could represent the state of the offset tree at a given point:
	 *
	 * - Tokens starting in the interval [0, 15) are aligned with the beginning of the file
	 * - Tokens starting in the interval [15, 30) are offset by 1 indent level from the `bar` token
	 * - Tokens starting in the interval [30, 43) are offset by 1 indent level from the `foo` token
	 * - Tokens starting in the interval [43, 820) are offset by 2 indent levels from the `bar` token
	 * - Tokens starting in the interval [820, ∞) are offset by 1 indent level from the `baz` token
	 *
	 * The `setDesiredOffsets` methods inserts ranges like the ones above. The third line above would be inserted by using:
	 * `setDesiredOffsets([30, 43], fooToken, 1);`
	 * @param {[number, number]} range A [start, end] pair. All tokens with range[0] <= token.start < range[1] will have the offset applied.
	 * @param {Token} fromToken The token that this is offset from
	 * @param {number} offset The desired indent level
	 * @param {boolean} force `true` if this offset should not use the normal collapsing behavior. This should almost always be false.
