Struct InvalidRecord 

pub struct InvalidRecord {
    pub path: String,
    pub reason: String,
}

Why a record does not satisfy its lexicon.

One flat error rather than an enum per constraint. The caller is an HTTP layer turning this into a 400 and the reader is the client that wrote the record, so the field that matters is the path, and a message it can print beats a variant it would have to match on.

Fields

path: String

Where in the record the failure is, as a dotted and indexed path.

reason: String

What was wrong, in a sentence.

Implementations

impl InvalidRecord

pub fn at(path: &str, reason: impl Into<String>) -> Self

A failure at a path.

pub fn under(self, parent: &str) -> Self

The same failure, with its path placed under parent. The root of a nested object is "" until its caller places it.

pub(crate) fn no_such_record(collection: &str) -> Self

The collection has no record definition in this catalog.

Trait Implementations

impl Clone for InvalidRecord

fn clone(&self) -> InvalidRecord

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InvalidRecord

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

Formats the value using the given formatter.

impl Display for InvalidRecord

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

Formats the value using the given formatter.

impl Error for InvalidRecord

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 InvalidRecord

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