//#region src/array/sorted-array-index-of.d.ts
/**
 * Finds the index of `value` within an already-sorted `sortedArray` using a
 * binary search, returning `-1` when it is not present. By default the *first*
 * matching index is returned; pass `rightmost: true` to get the *last* one.
 *
 * Consolidates the first-match and last-match variants behind a single options
 * argument. Unlike {@link sortedArrayInsertionIndex}, this searches for an existing value
 * rather than an insertion point, so it only accepts directly comparable
 * elements.
 * @param sortedArray - The already-sorted array to search. Not mutated.
 * @param value - The value to locate.
 * @param options - Optional behavior flags.
 * @param options.rightmost - Set to `true` to return the last matching index instead of the first. Defaults to `false`.
 * @returns The index of `value`, or `-1` when it is not found.
 * @example
 * // First matching index (the default)
 * sortedArrayIndexOf([10, 20, 30, 30, 40], 30);
 * // 2
 * @example
 * // Last matching index
 * sortedArrayIndexOf([10, 20, 30, 30, 40], 30, {rightmost: true});
 * // 3
 * @example
 * // Not found
 * sortedArrayIndexOf([10, 20, 40], 30);
 * // -1
