Enum MappingError 

pub enum MappingError {
    Empty,
    TooMany(usize),
    Duplicated {
        endpoint: String,
    },
    Endpoint(EndpointError),
    TooShortForObject(String),
    Schema(SchemaError),
}

Error returned by the interface mappings.

Variants

Empty

An interface must have at least one mapping.

TooMany(usize)

An interface can have at max MAX_INTERFACE_MAPPINGS mappings.

Duplicated

The endpoint of all the mappings of an interface must have an unique endpoint.

This includes the parameters.

Fields

endpoint: String

The first duplicated endpoint

Endpoint(EndpointError)

Couldn’t parse the mapping’s endpoint

TooShortForObject(String)

The object interface endpoints should have at least 2 levels.

Schema(SchemaError)

The interface schema is invalid for mapping.

Trait Implementations

impl Debug for MappingError

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

Formats the value using the given formatter.

impl Display for MappingError

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

Formats the value using the given formatter.

impl Error for MappingError

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.
