trait Sequ[+A] extends SeqLike[A]

This the base trait for all efficient sequence collections based on Array like classes, Arrays, ArrayBuffers etc. The final classes compile time wrap the platform Array and buffer classes. So currently there are just two classes for each type A, An ArrImut that wraps a standard immutable Array to produce an immutable array, and a ArrBuff that wraps an ArrayBuffer. Currently, this just in a standard ArrayBuffer. Where A is a compound value types or an AnyVal type. Note there is no generalised sumBy[B](f: A => B): B, method included, as it is more runtime efficient to include this as an extension method in the B companion object of the user created types.

def iFlatMap[ArrB <: Arr[_]](f: (Int, A) => ArrB)(implicit build: BuilderArrFlat[ArrB]): ArrB

Index with element flatMap. Applies the parameter function to the index and each respective element of this sequence.

Attributes

def mapUniqueSucc[B](f: A => ErrBi[_, B]): ErrBi[ExcFind, B]

Takes a function from A to ErrBi[?, B]. If the function applied to each element produces a single Good, it is returned else returns Bad.

def mapWithAcc[B, ArrB <: Arr[B], C](initC: C)(f: (C, A) => (B, C))(implicit ev: BuilderArrMap[B, ArrB]): ArrB

Maps from A to B like normal map,but has an additional accumulator of type C that is discarded once the traversal is completed. Note the function signature follows the foreach based convention of putting the collection element 2nd or last as seen for example in fold methods' (accumulator, element) => B signature.
