Struct JsonDecodeError 

pub struct JsonDecodeError { /* private fields */ }

An error from decoding a JsonValue into a typed value.

Implementations

impl JsonDecodeError

pub const fn new(kind: JsonDecodeErrorKind, message: &'static str) -> Self

Creates a decode error with a stable kind and an actionable message.

pub const fn kind(&self) -> JsonDecodeErrorKind

Returns the stable error category.

pub const fn message(&self) -> &'static str

Returns a human-readable message.

pub const fn unexpected_type(message: &'static str) -> Self

A value had a different JSON type than expected.

pub const fn missing_field(message: &'static str) -> Self

A required object field was missing.

pub const fn number(message: &'static str) -> Self

A number could not be represented by the target type.

Trait Implementations

impl Clone for JsonDecodeError

fn clone(&self) -> JsonDecodeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for JsonDecodeError

impl Debug for JsonDecodeError

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

Formats the value using the given formatter.

impl Display for JsonDecodeError

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

Formats the value using the given formatter.

impl Eq for JsonDecodeError

impl Error for JsonDecodeError

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 PartialEq for JsonDecodeError

fn eq(&self, other: &JsonDecodeError) -> 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.
