    MissingField(&'static str),
    DuplicateKey(&'static str),
    MissingKey(&'static str),
    InvalidVariant(String),
}

An error type for utility-macros

Variants

MissingField(&'static str)

A required field is None when calling Partial::type_() or `HasRequired::required()``

DuplicateKey(&'static str)

A duplicate key is found when calling Record::from_entries()

MissingKey(&'static str)

A key is missing when calling Record::from_entries()

InvalidVariant(String)

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
