ByteRange

ByteRange :: # (opaque)

A half-open range of UTF-8 bytes in an original text source.

from_bounds : U64, U64 -> Try(ByteRange, BoundsError)

Construct [start, end). Empty ranges are valid.

start : ByteRange -> U64

end : ByteRange -> U64

len : ByteRange -> U64

is_empty : ByteRange -> Bool

is_eq : ByteRange, ByteRange -> Bool

slice : ByteRange, Str -> Try(Str, SliceError)

Select this range as a seamless slice of source.

The returned string retains the source backing allocation and does not copy the selected bytes.

BoundsError : [EndBeforeStart]

SliceError : [NotScalarBoundary, OutOfBounds]
