Function to_string_value 

pub fn to_string_value(value: &Value) -> Result<String>

Serialize a Value directly to a YAML String, preserving Value::Tagged shape losslessly.

This function bypasses the Serialize pipeline entirely and writes the YAML-tag prefix directly. to_string/to_value also preserve Value::Tagged when T is (or contains) a Value — see the note on to_value — but this one skips the round trip through Serializer altogether.

Use this whenever you hold a Value that may contain Value::Tagged and want the emitted YAML to round-trip back into an equivalent Value::Tagged.

Examples

use noyalib::{from_str, to_string_value, Value};
let v: Value = from_str("!Color '#ff8800'\n").unwrap();
assert!(matches!(v, Value::Tagged(_)));
let s = to_string_value(&v).unwrap();
// Re-parsing yields an equivalent `Value::Tagged`.
let back: Value = from_str(&s).unwrap();
assert!(matches!(back, Value::Tagged(_)));
