Crate bam_builder 

Simple wrapper over rust_htslib::bam for building collections of BAM records for testing.

Provides an easy to use builder pattern for creating both paired end and single reads. Additionally this library provides nice wrappers and extensions on rust_htslib and intends to grow them over time.

• bam_order allows for specifying different sort orders for your BAM collection.
• sequence_dict is a SequenceDictionary like object used for generating rust_htslib::bam::Headers.
• wrappers provides some convenience types for awkward types like rust_htslib::bam::record::Aux.

Example

use bam_builder::{bam_order::BamSortOrder, BamBuilder};

let mut builder = BamBuilder::new(
    100,                    // default read length
    30,                     // default base quality
    "Pair".to_owned(),      // name of samples
    None,                   // optional read group id
    BamSortOrder::Unsorted, // how to sort reads when `.sort` is called
    None,                   // optional sequence_dict
    None,                   // seed used for generating random bases
);

// Create a builder for read pair spec
let records = builder
    .pair_builder()
    .contig(0)               // reads are mapped to tid 0
    .start1(0)               // start pos of read1
    .start2(200)             // start pos of read2
    .unmapped1(false)        // override default of unmapped
    .unmapped2(false)        // override default of unmapped
    .bases1("A".repeat(100)) // override default random bases with "A"s
    .bases2("C".repeat(100)) // override default random bases with "C"s
    .build()                 // inflate the underlying records and set mate info
    .unwrap();

// Inflate the underlying BAM bam records and add to builder
builder.add_pair(records);

// Write to temp file
let tmp = builder.to_tmp().unwrap();
