I'm trying to write a ULEB 128 parser that will take an array of unsigned bytes and return the value and shift required. If understand correctly if I have a ubyte[] list = [0x1b, 0x02, 0x03] then what I do is look at the 0x1b and here the high bit is greater than 0, so then I've to read the next byte. In the end it should return 0x20b with a shift of 2 without including 0x03, as the second byte high bit is 0. If my logic is correct, my main issue is byte manipulation in D i.e. how to check the high or low bits.

Like you would do in C. You can use bitwise and (&) and binary shift (<<).
If you need an example to go by, druntime does this:
