Enum SchemaError 

pub enum SchemaError {
    Schema(String),
    FieldType(String),
    FieldValue(String),
    FieldName(String),
    Validation(String),
    Serialization(String),
}

Errors produced when building, validating or (de)serializing a schema, a field entry, or a field value.

Variants

Schema(String)

The schema definition itself is invalid — for example a duplicate field name, an out-of-range index, or an incompatible upgrade.

FieldType(String)

A FieldType declaration is malformed (e.g. an unsupported nested type, an invalid Map key type, …).

FieldValue(String)

A FieldValue does not satisfy its declared FieldType.

FieldName(String)

A field name violates the rules enforced by validate_field_name.

Validation(String)

A document fails schema validation — usually because a required field is missing or because a field appears that the schema does not declare.

Serialization(String)

CBOR or serde (de)serialization failed.

Trait Implementations

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.
