(require file/xxhash32 ) package: xxhash-lib

procedure
( xxhash32 bs[seed])→(integer-in 04294967295)
bs:bytes?
seed:(integer-in 04294967295)=0

Computes the XXH32 hash of bs with the given seed.

procedure
( xxh32? v)→boolean?
v:any/c

procedure
( make-xxh32 [seed])→xxh32?
seed:(integer-in 04294967295)=0

procedure
( xxh32-reset! h[seed])→void?
h:xxh32?
seed:(integer-in 04294967295)=0

procedure
( xxh32-update! hbs[startend])→void?
h:xxh32?
bs:bytes?
start:exact-nonnegative-integer? =0
end:exact-nonnegative-integer? =(bytes-length bs)

procedure
( xxh32-digest h)→(integer-in 04294967295)
h:xxh32?

The make-xxh32 procedure returns a hashing context that can be used to compute an XXH32 digest using constant memory.

Examples:

> (require file/xxhash32)
> (define ctx(make-xxh32 ))
> (xxh32-update! ctx#"hello")
> (xxh32-update! ctx#" world!")
> (xxh32-digest ctx)
