Question: VCF file indexing function

[holtjma]

Hi,

I'm trying to find a function that will build a VCF index file (.tbi). I found one for BAM files that works great (https://docs.rs/rust-htslib/latest/rust_htslib/bam/index/fn.build.html), but I can't seem to find an equivalent for VCFs.

1. Does that equivalent exist?
2. If not, is the best way to tackle this by implementing a similar wrapper as the bam::index::build(...), but using https://docs.rs/rust-htslib/latest/rust_htslib/htslib/fn.bcf_index_build3.html as the interface to htslib?

Thanks in advance!
