Function to_value 

pub fn to_value<T: ?Sized + Serialize>(v: &T) -> Result<BorrowedValue<'static>>

Serialize a value to a BorrowedValue.

This is the low-level entry point — use to_string for a complete YAML string. Returning a BorrowedValue first is useful for inspection or transformation before emission.

Example

use serde::Serialize;
use yaml0::{to_value, BorrowedValue};

#[derive(Serialize)]
struct Point { x: i32, y: i32 }

let v = to_value(&Point { x: 1, y: 2 }).unwrap();
assert!(matches!(v, BorrowedValue::Map(_)));
