Function from_slice 

pub fn from_slice<T>(input: &[u8]) -> Result<T, DeserializeError<PostcardError>>
where
    T: Facet<'static>,

Deserialize a value from postcard bytes into an owned type.

This is the recommended default for most use cases. The input does not need to outlive the result, making it suitable for deserializing from temporary buffers (e.g., HTTP request bodies).

Types containing &str or &[u8] fields cannot be deserialized with this function; use String/Vec<u8> or Cow<str>/Cow<[u8]> instead. For zero-copy deserialization into borrowed types, use from_slice_borrowed.

Example

use facet::Facet;
use facet_postcard::from_slice;

#[derive(Facet, Debug, PartialEq)]
struct Point {
    x: i32,
    y: i32,
}

// Postcard encoding: [x=10 (zigzag), y=20 (zigzag)]
let bytes = &[0x14, 0x28];
let point: Point = from_slice(bytes).unwrap();
assert_eq!(point.x, 10);
assert_eq!(point.y, 20);
