Enum JsonError

#[non_exhaustive]
pub enum JsonError {
    NotOfType {
        target: String,
        of_type: JsonType,
    },

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

target is not of the correct type of_type ([JsonType]).

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.

NotMultiplesOfType

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

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.

JsonFieldMissingFromObject(String)

The given required field is missing from a JSON object.

JsonKeyMissing

A key is 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.

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.

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)>

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 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.
