Appply a strict left Fold to a lazy bytestring

Get the first byte of a byte stream or return Nothing if the stream is empty

Get the last byte of a byte stream or return Nothing if the byte stream is empty

Returns True if the byte stream is empty, False otherwise

Return the length of the byte stream in bytes

(any predicate) returns True if any byte satisfies the predicate, False otherwise

(all predicate) returns True if all bytes satisfy the predicate, False otherwise

Computes the maximum byte

Computes the minimum byte

(elem w8) returns True if the byte stream has a byte equal to w8, False otherwise

(notElem w8) returns False if the byte stream has a byte equal to w8, True otherwise

(find predicate) returns the first byte that satisfies the predicate or Nothing if no byte satisfies the predicate

(index n) returns the nth byte of the byte stream, or Nothing if the stream has an insufficient number of bytes

(elemIndex w8) returns the index of the first byte that equals w8, or Nothing if no byte matches

(findIndex predicate) returns the index of the first byte that satisfies the predicate, or Nothing if no byte satisfies the predicate
