TreeSerialize/TreeDeserialize with “JSON and /”.

Access items with '/' as path separator and JSON (from serde-json-core) as serialization/deserialization payload format.

Paths used here are reciprocal to TreeKey::path(..., "/")/TreeKey::iter_paths("/").

use miniconf::{JsonCoreSlash, Tree};
#[derive(Tree, Default)]
struct S {
    foo: u32,
    #[tree(depth=1)]
    bar: [u16; 2],
};
let mut s = S::default();
s.set_json("/bar/1", b"9").unwrap();
assert_eq!(s.bar[1], 9);
let mut buf = [0u8; 10];
let len = s.get_json("/bar/1", &mut buf[..]).unwrap();
assert_eq!(&buf[..len], b"9");

Required Methods

fn set_json( &mut self, path: &str, data: &'de [u8] ) -> Result<usize, Error<Error>>

Update a node by path.

Args

• path - The path to the node. Everything before the first '/' is ignored.
• data - The serialized data making up the content.

Returns

The number of bytes consumed from data or an Error.

fn get_json(&self, path: &str, data: &mut [u8]) -> Result<usize, Error<Error>>

Retrieve a serialized value by path.

Args

• path - The path to the node. Everything before the first '/' is ignored.
• data - The buffer to serialize the data into.

Returns

The number of bytes used in the data buffer or an Error.

fn set_json_by_key<K: IntoKeys>( &mut self, keys: K, data: &'de [u8] ) -> Result<usize, Error<Error>>

Update a node by key.

Returns

The number of bytes consumed from data or an Error.

fn get_json_by_key<K: IntoKeys>( &self, keys: K, data: &mut [u8] ) -> Result<usize, Error<Error>>

Retrieve a serialized value by key.

Returns

The number of bytes used in the data buffer or an Error.

Object Safety

This trait is not object safe.
