JSON AppendArrayCopy Example

Demonstrates the AppendArrayCopy function.

Note: This example requires Chilkat v9.5.0.82 or above.

Rust

let json = chilkat::JsonObject::new();
let _ = json.load("{ \"name\": \"John\", \"marbles\": 100 }");

let jarr = chilkat::JsonArray::new();
let _ = jarr.load("[ 1, 2, 3, \"apple\", \"orange\", [ 10, 20, 30 ], { \"name\": \"Alfred\"} ]");

// Copy the contents of jar to a new array member named "stuff".
let _ = json.append_array_copy("stuff", &jarr);

println!("{}", json.emit().unwrap_or_default());
// Expected output is:  {"name":"John","marbles":100,"stuff":[1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"}]}

// Note: The contents of the array were copied.
// If we modify the contents of jarr, it does not modify the array contained within "json" because it is a separate copy.
// For example:
let _ = jarr.add_int_at(-1, 2020);
println!("{}", jarr.emit().unwrap_or_default());
// Expected output: [1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"},2020]

println!("{}", json.emit().unwrap_or_default());
// Remains unchanged: {"name":"John","marbles":100,"stuff":[1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"}]}
