fin and vec
Vec
vec
provides few approache to work with Vec
:
naive
: explicit recusion- no need to keep constraints around for most functions
- simple
- slow
pull
:Vec n a
represented asFin n -> a
- Fuses well
- Some code is hard to write (e.g.
Traversable
) - relatively simple
inline
, usingInlineInduction
:- exploits how GHC dictionary resolution works
- makes code to unroll completely for staticaly known sizes
- fast in that case
Dependencies
And with dependency flags turned off:
Benchmarks: dotProduct
list
version sets the baseline, built-in fusion seems to kick in.vector
andunboxed
vector are 3x slower.- this library, naive
vec
is even slower Data.Vec.Pull
approach is slower, except- that without conversions it's up to speed with
vector
inline
(usingInlineInduction
over size) is faster than list version.
