Struct JsonError 

pub struct JsonError {
    pub kind: JsonErrorKind,
    pub span: Option<Span>,
    pub source_code: Option<String>,
}

Error type for JSON deserialization.

Fields

kind: JsonErrorKind

The specific kind of error

span: Option<Span>

Source span where the error occurred

source_code: Option<String>

The source input (for diagnostics)

Implementations

impl JsonError

pub fn new(kind: JsonErrorKind, span: Span) -> Self

Create a new error with span information

pub fn without_span(kind: JsonErrorKind) -> Self

Create an error without span information

pub fn with_source(self, source: &str) -> Self

Attach source code for rich diagnostics

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, f: &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<ReflectError> for JsonError

fn from(err: ReflectError) -> Self

Converts to this type from the input type.
