Function tskit::bindings::tsk_variant_decode

pub unsafe extern "C" fn tsk_variant_decode(
    self_: *mut tsk_variant_t,
    site_id: tsk_id_t,
    options: tsk_flags_t
) -> c_int

@brief Decode the genotypes at the given site, storing them in this variant.

@rst Decodes the genotypes for this variant’s samples, indexed to this variant’s alleles, at the specified site. This method is most efficient at decoding sites in-order, either forwards or backwards along the tree sequence. Resulting genotypes are stored in the genotypes member of this variant. @endrst

@param self A pointer to an initialised tsk_variant_t object. @param site_id A valid site id for the tree sequence of this variant. @param options Bitwise option flags. Currently unused; should be set to zero to ensure compatibility with later versions of tskit. @return Return 0 on success or a negative value on failure.
