All errors related to JSON validation/parsing.

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.

NotOfType

Fields

target: String

An arbitrary “target” that doesn’t have the required type.

of_type: JsonType

The JSON type the target was expected to be.

Signals that target is not of type of_type (JsonType).

NotMultiplesOfType

Fields

target: String

An arbitrary “target” where each or one of it’s elements doesn’t have the required type.

of_type: JsonType

The JSON type the element was expected to be.

Like JsonError::NotOfType, only called when the target is a multiple; array, set, etc.

JsonFieldMissingFromObject(String)

Signals that a specific field is missing from a JSON object.

JsonKeyMissing

Fields

for_target: String

The target from which the key is missing.

type_of: String

The kind of thing the key indicates.

with_key: String

The key that is missing.

Signals a key missing from a JSON object.

Note that this is different from JsonError::JsonFieldMissingFromObject, this error talks about an expected identifying key ("ed25519:abcd") missing from a target, where the key has a specific “type”/name.

Serde(Error)

A more generic JSON error from serde_json.

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for JsonError

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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

impl From<Error> for JsonError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<JsonError> for Error

fn from(source: JsonError) -> Self

Converts to this type from the input type.
