Struct JsonFlattener 

pub struct JsonFlattener<'a> {
    pub separator: &'a str,
    pub alt_array_flattening: bool,
    pub preserve_arrays: bool,
}

JsonFlattener is the main driver when flattening JSON

Examples

use nu_utils;

let flattener = nu_utils::JsonFlattener { ..Default::default() };

Fields

separator: &'a str

Alternate separator used between keys when flattening

Examples

use nu_utils;
let flattener = nu_utils::JsonFlattener { separator: "_", ..Default::default()};

alt_array_flattening: bool

Opinionated flattening format that places values in an array if the object is nested inside an array

Examples

use nu_utils;
let flattener = nu_utils::JsonFlattener { alt_array_flattening: true, ..Default::default()};

preserve_arrays: bool

Completely flatten JSON and keep array structure in the key when flattening

Examples

use nu_utils;
let flattener = nu_utils::JsonFlattener { preserve_arrays: true, ..Default::default()};

Implementations

impl JsonFlattener<'_>

This implementation defines the core usage for the JsonFlattener structure.

Examples

use nu_utils;
use serde_json::json;

let flattener = nu_utils::JsonFlattener::new();
let example = json!({
    "a": {
        "b": "c"
    }
 });

let flattened_example = flattener.flatten(&example);

pub fn new() -> Self

Returns a flattener with the default arguments

Examples

use nu_utils;

let flattener = nu_utils::JsonFlattener::new();

pub fn flatten(&self, json: &SerdeValue) -> SerdeValue

Flattens JSON variants into a JSON object

Arguments

• json - A serde_json Value to flatten

Examples

use nu_utils;
use serde_json::json;

let flattener = nu_utils::JsonFlattener::new();
let example = json!({
    "name": "John Doe",
    "age": 43,
    "address": {
        "street": "10 Downing Street",
        "city": "London"
    },
    "phones": [
        "+44 1234567",
        "+44 2345678"
    ]
 });

let flattened_example = flattener.flatten(&example);

Trait Implementations

impl Default for JsonFlattener<'_>

fn default() -> Self

Returns the “default value” for a type.
