Struct DataError 

pub struct DataError {
    pub path: String,
    pub kind: ErrorKind,
}

Where in a value a problem was found, and what it was.

The path is carried because these values nest arbitrarily and a record is rejected wholesale: “a float” is a much slower thing to act on than “post.embed.images[1].aspectRatio.width is a float”.

Fields

path: String

A dotted and bracketed path from the root of the value.

kind: ErrorKind

What was wrong there.

Implementations

impl DataError

fn at(path: &str, kind: impl Into<ErrorKind>) -> Self

Builds an error at path.

Trait Implementations

impl Clone for DataError

fn clone(&self) -> DataError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataError

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

Formats the value using the given formatter.

impl Display for DataError

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

Formats the value using the given formatter.

impl Error for DataError

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 PartialEq for DataError

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