Struct Json 

pub struct Json;

Parser for the json format: standard JSON into a source-located value tree.

Objects, arrays, and scalars map to the value tree with a per-node span Location; JSON null is rejected with Error::UnsupportedNull. Stateless — construct with Json::new.

use tanzim_parse::{Parse, json::Json};
use tanzim_source::SourceBuilder;

let source = SourceBuilder::new()
    .with_source("file")
    .with_resource("config.json")
    .build()
    .unwrap();
let value = Json::new().parse(&source, br#"{"port":8080}"#).unwrap();
let port = value.value.as_map().unwrap().get("port").unwrap();
assert_eq!(port.value.as_int().unwrap(), 8080);

Implementations

impl Json

pub fn new() -> Self

Create a JSON parser.

Trait Implementations

impl Clone for Json

fn clone(&self) -> Json

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Json

impl Default for Json

fn default() -> Json

Returns the “default value” for a type.

impl Parse for Json

fn name(&self) -> &str

Human-readable name used in error messages.

fn supported_format_list(&self) -> Vec<String>

Format extensions this parser handles (e.g. ["json"], ["yml", "yaml"]).

fn parse(&self, src: &Source, bytes: &[u8]) -> Result<LocatedValue, Error>

Parse bytes into a LocatedValue tree.

fn is_format_supported(&self, bytes: &[u8]) -> Option<bool>

Probe bytes for auto-detection when Payload::maybe_format is None.
