Expand description

A trait for a BCF reader with a read method.

Required methods

Read the next record.

Arguments

  • record - an empty record, that can be created with bcf::Reader::empty_record.

Returns

None if end of file was reached, otherwise Some will contain a result with an error in case of failure.

Return an iterator over all records of the VCF/BCF file.

Return the header.

Return empty record. Can be reused multiple times.

Activate multi-threaded BCF/VCF read support in htslib. This should permit faster reading of large VCF files.

Setting nthreads to 0 does not change the current state. Note that it is not possible to set the number of background threads below 1 once it has been set.

Arguments

  • n_threads - number of extra background writer threads to use, must be > 0.
