pub struct Info { /* private fields */ }
Expand description

A VCF header information record (INFO).

Implementations

Converts a generic VCF header record to a VCF header info record.

Examples
use noodles_vcf::header::{
    info::{Key as InfoKey, Type},
    record::{Key as RecordKey, Value},
    FileFormat, Info, Number, Record,
};

let record = Record::new(
    RecordKey::Info,
    Value::Struct(vec![
        (String::from("ID"), String::from("NS")),
        (String::from("Number"), String::from("1")),
        (String::from("Type"), String::from("Integer")),
        (
            String::from("Description"),
            String::from("Number of samples with data"),
        ),
    ]),
);

assert_eq!(
    Info::try_from_record_file_format(record, FileFormat::new(4, 3)),
    Ok(Info::new(
        InfoKey::SamplesWithDataCount,
        Number::Count(1),
        Type::Integer,
        String::from("Number of samples with data"),
    ))
);

Creates a VCF header information record.

Examples
use noodles_vcf::header::{info::{Key, Type}, Info, Number};

let info = Info::new(
    Key::SamplesWithDataCount,
    Number::Count(1),
    Type::Integer,
    String::from("Number of samples with data"),
);

Returns the information field key.

Examples
use noodles_vcf::header::{info::Key, Info};
let info = Info::from(Key::SamplesWithDataCount);
assert_eq!(info.id(), &Key::SamplesWithDataCount);

Returns the cardinality of the information field value.

Examples
use noodles_vcf::header::{info::Key, Info, Number};
let info = Info::from(Key::SamplesWithDataCount);
assert_eq!(info.number(), Number::Count(1));

Returns the type of the information field value.

Examples
use noodles_vcf::header::{info::{Key, Type}, Info};
let info = Info::from(Key::SamplesWithDataCount);
assert_eq!(info.ty(), Type::Integer);

Returns the description of the information field.

Examples
use noodles_vcf::header::{info::Key, Info};
let info = Info::from(Key::SamplesWithDataCount);
assert_eq!(info.description(), "Number of samples with data");

Returns the index of the ID in the dictionary of strings.

This is typically used in BCF.

Examples
use noodles_vcf::header::{info::Key, Info};
let info = Info::from(Key::SamplesWithDataCount);
assert!(info.idx().is_none());

Returns the extra fields in the record.

This includes fields other than ID, Number, Type, Description, and IDX.

Examples
use noodles_vcf::header::{info::Key, Info};
let info = Info::from(Key::SamplesWithDataCount);
assert!(info.fields().is_empty());
