1//! Serializer options for YAML emission.
2//!
3//! Controls indentation and optional anchor name generation for the serializer.
4//!
5//! Example: use 4-space indentation and a custom anchor naming scheme.
6//!
7//! ```rust
8//! use serde::Serialize;
9//!
10//! #[derive(Serialize)]
11//! struct Item { a: i32, b: bool }
12//!
13//! let mut buf = String::new();
14//! let opts = serde_saphyr::SerializerOptions {
15//!     indent_step: 4,
16//!     anchor_generator: Some(|id| format!("id{}/", id)),
17//! };
18//! serde_saphyr::to_fmt_writer_with_options(&mut buf, &Item { a: 1, b: true }, opts).unwrap();
19//! assert!(buf.contains("a: 1"));
20//! ```
