Struct Json 

pub struct Json { /* private fields */ }

Implementations

impl Json

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

Deserializes the JSON data into a custom type.

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

Type Parameters

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

Returns

• Ok(T) - The deserialized configuration object
• Err(serde_json::Error) - If deserialization fails due to format mismatches, missing fields, or type conversion failures

Errors

This method will return an error if:

• The JSON structure doesn’t match the expected type
• Required fields are missing from the JSON
• Type conversion fails (e.g., string to number)
• The JSON is malformed or invalid

Examples

use serde::{Deserialize, Serialize};
use serde_json::json;
use apollo_client::namespace::json::Json;

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

let json_data = json!({
    "host": "localhost",
    "port": 5432
});

let json_namespace = Json::from(json_data);
let config: DatabaseConfig = json_namespace.to_object()?;

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 Debug for Json

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

Formats the value using the given formatter.

impl From<Json> for JsValue

fn from(val: Json) -> Self

Converts to this type from the input type.

impl Serialize for Json

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<Value> for Json

Converts a serde_json::Value into a Json instance.

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

Arguments

• json_value - The raw JSON value containing configuration data

Returns

• Ok(Json) - A new Json instance containing the parsed configuration
• Err(Error::ContentNotFound) - If the JSON value doesn’t contain a “content” field
• Err(Error::DeserializeError) - If the content field cannot be parsed as valid JSON

Errors

This function will return an error if:

• The JSON value doesn’t contain a “content” field
• The “content” field is not a string
• The content string cannot be parsed as valid JSON

Examples

use serde_json::json;
use apollo_client::namespace::json::Json;

let json_data = json!({"content": "{\"key\": \"value\"}"});
let json_namespace = Json::try_from(json_data)?;

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.
