Enum JsonError 

#[non_exhaustive]
pub enum JsonError {
    Serialize {
        source: Error,
    },
    Deserialize {
        source: Error,
    },
}

Available on crate feature json only.

JsonSerializer failures. Display names the operation, the error class (serde_json::error::Category), and the line/column — never serde_json::Error’s own message, which for a data error embeds a fragment of the value it rejected (e.g. invalid type: string "sk-live-…", expected u64). The full underlying error, message included, is still reachable via std::error::Error::source for a caller that deliberately wants it — that caller’s own logging then owns not leaking a payload fragment, the same rule this type upholds by default.

Debug is a manual impl, never derived: serde_json::Error’s own Debug embeds its Display message (the same payload fragment Display above must avoid), so deriving here would leak through {:?} even though Display is safe.

use reliar_core::{JsonSerializer, Serializer};

#[derive(serde::Serialize, serde::Deserialize)]
struct Ping;
impl reliar_core::Message for Ping {
    const TYPE: &'static str = "ping";
    const VERSION: u16 = 1;
}

let result = JsonSerializer.deserialize::<Ping>(b"not json");
let err = match result {
    Ok(_) => unreachable!("not valid JSON"),
    Err(err) => err,
};
// The message never echoes a fragment of the rejected payload.
assert!(err.to_string().starts_with("failed to deserialize from JSON:"));

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Serialize

Serializing a body to JSON failed.

Fields

source: Error

The underlying serde_json error.

Deserialize

Deserializing bytes into a body failed.

Fields

source: Error

The underlying serde_json error.

Trait Implementations

impl Debug for JsonError

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

Formats the value using the given formatter.

impl Display for JsonError

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

Formats the value using the given formatter.

impl Error for JsonError

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.
