Struct TaggedValue 

pub struct TaggedValue { /* private fields */ }

A tagged YAML value.

Represents a value with an explicit YAML tag, such as !custom_type value. Tags are used to specify the type or interpretation of a value.

Examples

use noyalib::{Tag, TaggedValue, Value};

let tagged = TaggedValue::new(
    Tag::new("!timestamp"),
    Value::String("2024-01-01".to_string()),
);
assert_eq!(tagged.tag().as_str(), "!timestamp");

Implementations

impl TaggedValue

pub fn new(tag: Tag, value: Value) -> TaggedValue

Creates a new tagged value.

Examples

use noyalib::{Tag, TaggedValue, Value};
let tv = TaggedValue::new(Tag::new("!Custom"), Value::from("hello"));
assert_eq!(tv.tag().as_str(), "!Custom");
assert_eq!(tv.value().as_str(), Some("hello"));

pub fn tag(&self) -> &Tag

Returns a reference to the tag.

Examples

use noyalib::{Tag, TaggedValue, Value};
let tv = TaggedValue::new(Tag::new("!Color"), Value::from("#ff8800"));
assert_eq!(tv.tag().as_str(), "!Color");

pub fn value(&self) -> &Value

Returns a reference to the inner value.

Examples

use noyalib::{Tag, TaggedValue, Value};
let tv = TaggedValue::new(Tag::new("!Color"), Value::from("#ff8800"));
assert_eq!(tv.value().as_str(), Some("#ff8800"));

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

Returns a mutable reference to the inner value.

Examples

use noyalib::{Tag, TaggedValue, Value};
let mut tv = TaggedValue::new(Tag::new("!Color"), Value::from("#000"));
*tv.value_mut() = Value::from("#ff8800");
assert_eq!(tv.value().as_str(), Some("#ff8800"));

pub fn into_parts(self) -> (Tag, Value)

Consumes the tagged value and returns the tag and value as separate owned components.

Examples

use noyalib::{Tag, TaggedValue, Value};
let tv = TaggedValue::new(Tag::new("!Custom"), Value::from(42_i64));
let (tag, value) = tv.into_parts();
assert_eq!(tag.as_str(), "!Custom");
assert_eq!(value.as_i64(), Some(42));
