Enum Error 

pub enum Error {
    ContentNotFound,
    DeserializeError(Error),
}

Comprehensive error types that can occur when working with JSON namespaces.

This enum covers all possible error conditions that may arise during JSON namespace operations, from content extraction to deserialization failures.

Error Categories

• Content Errors: Issues with extracting content from JSON values
• Deserialization Errors: Problems with parsing JSON into custom types

Examples

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

#[derive(Debug, Deserialize, Serialize)]
struct MyType {
    name: String,
    value: i32,
}

// Create a sample JSON namespace
let json_data = json!({
    "content": r#"{"name": "test", "value": 42}"#
});
let json_namespace = Json::try_from(json_data).unwrap();

match json_namespace.to_object::<MyType>() {
    Ok(config) => {
        // Handle successful deserialization
        println!("Config: {:?}", config);
    }
    Err(serde_error) => {
        // Handle JSON parsing errors
        eprintln!("JSON parsing failed: {}", serde_error);
    }
}

Variants

ContentNotFound

Failed to extract content from the JSON value.

This error occurs when the JSON value doesn’t contain the expected “content” field or when the content field is not a string.

DeserializeError(Error)

Failed to deserialize JSON value into the target type.

This error occurs when the JSON content cannot be parsed into the requested type due to format mismatches, missing fields, or type conversion failures.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
