Enum JsonFromStrError 

#[non_exhaustive]
pub enum JsonFromStrError {
    Parse(JsonError),
    Decode(JsonDecodeError),
}

The error type of from_json_str: either the input was not valid JSON, or the parsed value did not match the target type.

#[non_exhaustive]: new variants may be added in a future release.

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.

Parse(JsonError)

The input was not valid JSON.

Decode(JsonDecodeError)

The JSON parsed but did not match the target type.

Trait Implementations

impl Clone for JsonFromStrError

fn clone(&self) -> JsonFromStrError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for JsonFromStrError

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

Formats the value using the given formatter.

Formats the value using the given formatter.

impl Eq for JsonFromStrError

impl Error for JsonFromStrError

Available on crate feature std only.

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<JsonDecodeError> for JsonFromStrError

fn from(error: JsonDecodeError) -> Self

Converts to this type from the input type.

impl From<JsonError> for JsonFromStrError

fn from(error: JsonError) -> Self

Converts to this type from the input type.

impl PartialEq for JsonFromStrError

fn eq(&self, other: &JsonFromStrError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
