Struct UnexpectedValue

pub struct UnexpectedValue { /* private fields */ }

Error caused when trying to convert JsonValue into some wrong type value.

use tinyjson::{JsonValue, UnexpectedValue};
use std::convert::TryFrom;

let error = String::try_from(JsonValue::from(1.0)).unwrap_err();
assert!(matches!(error, UnexpectedValue{..}));

Implementations

impl UnexpectedValue

pub fn value(&self) -> &JsonValue

Get reference to the value which failed to be converted.

use tinyjson::JsonValue;
use std::convert::TryFrom;

let error = String::try_from(JsonValue::from(1.0)).unwrap_err();
assert_eq!(error.value(), &JsonValue::Number(1.0));

Trait Implementations

impl Debug for UnexpectedValue

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

Formats the value using the given formatter.

impl Display for UnexpectedValue

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

Formats the value using the given formatter.

impl Error for UnexpectedValue

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<UnexpectedValue> for JsonValue

Convert this error into the value which failed to be converted.

use tinyjson::JsonValue;
use std::convert::TryFrom;

let error = String::try_from(JsonValue::from(1.0)).unwrap_err();
assert_eq!(JsonValue::from(error), JsonValue::Number(1.0));

fn from(err: UnexpectedValue) -> Self

Converts to this type from the input type.
