// Chunk is a description of a RandomRun slice.

// Used to say which part of a given RandomRun will be shrunk by some
|
|
// ShrinkCommand.

|
|
// For a RandomRun [0,1,2,3,4,5,6,7,8], the Chunk{size=4, index=2} means this:
|
|
// [_,_,X,X,X,X,_,_,_]
|
|
//
|
|
// Different ShrinkCommands will use the Chunk in different ways.
|
|
// A few examples:
|
|
//
|
|
// Original RandomRun: [5,1,3,9,4,2,3,0]
|
|
// Chunk we'll show off: [_,_,X,X,X,X,_,_]
|
|
//
|
|
// ZeroChunk: [5,1,0,0,0,0,3,0]
|
|
// SortChunk: [5,1,2,3,4,9,3,0]
|
|
// DeleteChunkAndMaybeDecPrevious: [5,1, 3,0]
