//! Encode at 10-bit depth using [`avif::EncoderConfig`].
//!
//! Bit depth is the one encoder setting without a builder method, so it's set by constructing an
//! [`avif::EncoderConfig`] and passing it to [`avif::AvifEncoder::new_with_config`]. After encoding we probe the output
//! to confirm the stored depth is 10-bit.
//!
//! Run with:
//!
//! ```text
//! cargo run --example high_bit_depth
//! ```
