Enum SchemaError 

pub enum SchemaError {
    NotAnObject {
        path: String,
    },
    NoType {
        path: String,
    },
    BadKeyword {
        path: String,

Why a lexicon document could not be turned into a schema tree.

Every one of these is a defect in a lexicon document rather than in a record. For the documents this project embeds it is a build-time bug, and the unit tests in this module are what catch it.

Variants

NotAnObject

A definition or property was not a JSON object.

Fields

path: String

Where in the document it sits.

NoType

A schema had no type.

Fields

path: String

Where in the document it sits.

BadKeyword

A keyword held the wrong kind of JSON value.

Fields

path: String

Where in the document it sits.

keyword: &'static str

The keyword that was wrong.

expected: &'static str

What it should have been.

RecordWithoutSchema

A record definition had no record object.

Fields

path: String

Where in the document it sits.

NotADefinition

A type that is only a field type appeared in definition position.

unknown and ref describe a slot inside a schema: “whatever the writer put here” and “look over there”. Neither says anything a document could define, so upstream refuses both under defs.

Fields

path: String

Where in the document it sits.

kind: &'static str

The type as written.

PrimaryNotMain

A primary definition was named something other than main.

Records and methods are addressed by the NSID of the document holding them, so a second one in the same document has no name to be reached by; the specification puts the primary under main and only main.

Fields

path: String

Where in the document it sits.

kind: &'static str

The type as written.

Trait Implementations

impl Clone for SchemaError

fn clone(&self) -> SchemaError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SchemaError

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

Formats the value using the given formatter.

impl Display for SchemaError

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

Formats the value using the given formatter.

impl Error for SchemaError

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 SchemaError

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