Struct Yaml 

pub struct Yaml;

Parser for the yml/yaml formats: YAML into a source-located value tree.

Mappings, sequences, and scalars map to the value tree with a per-node marker Location; YAML null becomes Value::Null. Stateless — construct with Yaml::new.

use tanzim_parse::{Parse, yaml::Yaml};
use tanzim_source::SourceBuilder;

let source = SourceBuilder::new()
    .with_source("file")
    .with_resource("config.yaml")
    .build()
    .unwrap();
let value = Yaml::new().parse(&source, b"port: 8080\n").unwrap();
let port = value.value().as_map().unwrap().get("port").unwrap();
assert_eq!(port.value().as_int().unwrap(), 8080);

Implementations

fn clone(&self) -> Yaml

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Yaml

impl Default for Yaml

fn default() -> Yaml

Returns the “default value” for a type.

impl Parse for Yaml

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>
