Struct DeserError

pub struct DeserError<'input, 'shape, C = Cooked> {
    pub input: Cow<'input, [u8]>,
    pub span: Span<C>,
    pub kind: DeserErrorKind<'shape>,
    pub source_id: &'static str,
}

A JSON parse error, with context. Never would’ve guessed huh.

Fields

input: Cow<'input, [u8]>

The input associated with the error.

span: Span<C>

Where the error occured

kind: DeserErrorKind<'shape>

The specific error that occurred while parsing the JSON.

source_id: &'static str

The source identifier for error reporting

Implementations

impl<'input, 'shape, C> DeserError<'input, 'shape, C>

pub fn into_owned(self) -> DeserError<'static, 'shape, C>

Converts the error into an owned error.

pub fn with_span<D>(self, span: Span<D>) -> DeserError<'input, 'shape, D>

Sets the span of this error

impl<'input, 'shape, C> DeserError<'input, 'shape, C>

pub fn new<I>( kind: DeserErrorKind<'shape>, input: &'input I, span: Span<C>, source_id: &'static str, ) -> DeserError<'input, 'shape, C>

where I: 'input + InputDebug + ?Sized,

Creates a new deser error, preserving input and location context for accurate reporting.

pub fn with_source_id( self, source_id: &'static str, ) -> DeserError<'input, 'shape, C>

Sets the source ID for this error

pub fn message(&self) -> DeserErrorMessage<'_, '_, C>

Provides a human-friendly message wrapper to improve error readability.

Trait Implementations

impl Debug for DeserError<'_, '_>

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

Formats the value using the given formatter.

impl Display for DeserError<'_, '_>

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

Formats the value using the given formatter.

impl Error for DeserError<'_, '_>

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.
