Enum Error

pub enum Error {
    Unstructured(Vec<Cow<'static, str>>),
    Structured(BTreeMap<Location, Error>),
}

A type that represents all validation issues that arise during the validation of the given data type.

Variants

Unstructured(Vec<Cow<'static, str>>)

A flat, unstructured list of failure reasons

Structured(BTreeMap<Location, Error>)

A structured, potentially nested set of failure reasons

a vector or a nested map can attribute errors to the correct locations

Implementations

impl Error

pub fn new<S>(message: S) -> Self

where S: Into<Cow<'static, str>>,

Constructs a new unstructured Error with a single message

let e = Error::new("the universe divided by 0");

pub fn merge(&mut self, other: Error)

Merge 2 existing Error types

let mut e1 = Error::new("the universe divided by 0");
let e2 = Error::new("an unstoppable force collided with an improvable object");

e1.merge(e2);

pub fn build() -> ErrorBuilder

create a new ErrorBuilder instance

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

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.

impl PartialEq for Error

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

impl Serialize for Error

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
