Clojure Confusion

Clojure Confusion

Sometimes it works...

Digest:   [18 8c ab df 4a 78 3a 31 2e 9a 57 94 a8 b 76 42 6c 12 3d 83]
Offset:   3
Excerpt:  [df 4a 78 3a]
Unsigned: [5f 4a 78 3a]
Squashed: 5f4a783a

------------------

But sometimes it gives up part way and fills the rest of the Long with 1s.

Digest:   [fd f8 d7 e1 2f fa b7 c3 83 52 96 82 19 da 1f f3 c3 53 fa 71]
Offset:   1
Excerpt:  [f8 d7 e1 2f]
Unsigned: [78 d7 e1 2f]
Squashed: ffffffffffffe12f

------------------

Which doesn't really make a ton of sense because when I run the exact same thing manually, it works as expected.

(format "%x" (shift-byte-vector-into-long [0x78 0xd7 0xe1 0x2f]))
"78d7e12f"
