Struct Yaml

pub struct Yaml { /* private fields */ }

A wrapper around serde_yaml::Value for YAML-formatted configuration data.

This struct provides a type-safe interface for working with YAML configuration data retrieved from Apollo. It maintains the original YAML structure while providing convenient methods for deserialization into custom types.

Thread Safety

This struct is Clone and Debug, making it easy to work with in concurrent environments. The underlying serde_yaml::Value is also thread-safe.

Examples

use serde_yaml;
use apollo_client::namespace::yaml::Yaml;

let yaml_data = serde_yaml::from_str("database:\n  host: localhost\n  port: 5432").unwrap();

let yaml_namespace = Yaml::from(yaml_data);

Implementations

impl Yaml

pub fn to_object<T: DeserializeOwned>(&self) -> Result<T, Error>

Deserializes the YAML data into a custom type.

This method attempts to deserialize the stored YAML value into any type that implements DeserializeOwned. This is useful for converting the raw YAML configuration into strongly-typed structs.

Type Parameters

• T - The target type to deserialize into. Must implement DeserializeOwned.

Returns

An instance of type T containing the deserialized data.

Examples

use serde::{Deserialize, Serialize};
use serde_yaml;
use apollo_client::namespace::yaml::Yaml;

#[derive(Deserialize, Serialize)]
struct DatabaseConfig {
    host: String,
    port: u16,
}

let yaml_data = serde_yaml::from_str("host: localhost\nport: 5432").unwrap();

let yaml_namespace = Yaml::from(yaml_data);
let config: DatabaseConfig = yaml_namespace.to_object().unwrap();

Trait Implementations

impl Clone for Yaml

fn clone(&self) -> Yaml

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Yaml

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Yaml> for JsValue

fn from(val: Yaml) -> Self

Converts to this type from the input type.

impl TryFrom<Value> for Yaml

Converts a serde_json::Value into a Yaml instance.

This implementation allows for easy creation of Yaml instances from raw JSON data, typically used by the namespace detection system.

Examples

use serde_json::json;
use apollo_client::namespace::yaml::Yaml;

let json_data = json!({"content": "name: MyApp\nversion: 1.0.0"});
let yaml_namespace = Yaml::try_from(json_data).unwrap();

type Error = Error

The type returned in the event of a conversion error.

fn try_from(json_value: Value) -> Result<Self, Self::Error>

Performs the conversion.
