Struct ParseError 

#[non_exhaustive]
pub struct ParseError(/* private fields */);

JSON deserialize / parse error reported by the underlying JSON parser.

The inner third-party error type is private; callers diagnose the failure via the accessor methods on this wrapper, all of which return primitive types or the workspace-local ParseCategory enum. The wrapper exists so that the ClientError::Parse variant payload is insulated from a future JSON-parser swap (bd:JMAP-6r7c.26).

Construct via ClientError::from_parse (the common path) or ParseError::from_serde_json (the low-level path that returns a wrapper without classifying it into a ClientError variant).

Implementations

impl ParseError

pub fn from_serde_json(e: Error) -> Self

Wrap a serde_json::Error into a ParseError.

Most callers want ClientError::from_parse which wraps and classifies in one step; this lower-level constructor is for callers that need to hold a ParseError before deciding whether to surface it as ClientError::Parse or in some other variant.

pub fn line(&self) -> usize

One-based line number where parsing failed, or 0 if the parser does not report a line number for this error category.

pub fn column(&self) -> usize

One-based column number where parsing failed, or 0 if the parser does not report a column number for this error category.

pub fn classify(&self) -> ParseCategory

Coarse-grained category of the failure.

See ParseCategory for the variant set and what each one means.

Trait Implementations

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Error for ParseError

fn source(&self) -> Option<&(dyn StdError + '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.
