Macro crab_nbt::nbt

macro_rules! nbt {
    ($name:literal, $content:tt) => { ... };
    ($name:expr, $content:tt) => { ... };
}

Macro that simplifies the creation of NBT using JSON/SNBT-like syntax. It takes a name and a content block, and returns an Nbt object.

Examples

Basic usage:

use bytes::Bytes;
use crab_nbt::nbt;

let key = "key".to_owned();
let value = Bytes::from(vec![0, 1, 2, 3]);
let nbt = nbt!("root nbt_inner name", {
    "float": 1.0,
    key: "value",
    "long_array": [L; 1, 2],
    "int_array": [Int; 1, 10, 25],
    "byte_array": [B; 0, 1, 0, 0, 1],
    "list": ["a", "b", "c"],
    "nbt_inner": {
        "key": "sub value"
    },
    "byte_array": value,
});

// The macro can also take variables to use data calculated at runtime
let var_as_key = "some_key".to_owned();
let other_key = "other_key".to_owned();
let value = vec![0, 1, 2];
let other_value = vec![3, 2, 1];
let nbt =  nbt!("root", {
    var_as_key: "wohoo!",
    "the_other_way": value,
    other_key: other_value,
});

This will create an Nbt object with the name “root” and the specified content.

Parameters

• name: The name of the NBT. This should be a string literal.
• content: The content of the NBT. This should be a block containing key-value pairs, where the keys are string literals and the values are valid NBT data types.

Returns

An Nbt object with the specified name and content.
