Struct noodles_vcf::record::info::field::Field

pub struct Field { /* private fields */ }

A VCF record info field.

Implementations

impl Field

pub fn try_from_str(s: &str, infos: &Infos) -> Result<Self, ParseError>

Parses a raw VCF record info field.

pub fn new(key: Key, value: Option<Value>) -> Self

Creates a VCF record info field.

Examples

use noodles_vcf::record::info::{field::{Key, Value}, Field};
let field = Field::new(Key::SamplesWithDataCount, Some(Value::Integer(1)));

pub fn key(&self) -> &Key

Returns the field key.

Examples

use noodles_vcf::record::info::{field::{Key, Value}, Field};
let field = Field::new(Key::SamplesWithDataCount, Some(Value::Integer(1)));
assert_eq!(field.key(), &Key::SamplesWithDataCount);

pub fn value(&self) -> Option<&Value>

Returns the field value.

Examples

use noodles_vcf::record::info::{field::{Key, Value}, Field};
let field = Field::new(Key::SamplesWithDataCount, Some(Value::Integer(1)));
assert_eq!(field.value(), Some(&Value::Integer(1)));

pub fn value_mut(&mut self) -> &mut Option<Value>

Returns a mutable reference to the value.

Examples

use noodles_vcf::record::info::{field::{Key, Value}, Field};
let mut field = Field::new(Key::SamplesWithDataCount, Some(Value::Integer(1)));
*field.value_mut() = Some(Value::Integer(2));
assert_eq!(field.value(), Some(&Value::Integer(2)));
