An immutable vector of bytes, backed by a balanced binary tree of chunks. Most operations are logarithmic in the depth of this tree, including
++,:+,+:,update, andinsert. Where possible, operations return lazy views rather than copying any underlying bytes. Usecopyto copy all underlying bytes to a fresh, array-backedByteVector.Unless otherwise noted, operations follow the same naming as the scala standard library collections, though this class does not extend any of the standard scala collections. Use
toIndexedSeq,toSeq, ortoIterableto obtain a regularscala.collectiontype.
