Enum RanvierError 

pub enum RanvierError {
    Message(String),
    NotFound(String),
    Validation(String),
    Internal(String),
}

A serde-compatible error type for common Ranvier patterns.

This satisfies all Axon bounds (Serialize + DeserializeOwned + Send + Sync + Debug) and provides typed variants for frequent error categories.

When to Use

• Prototyping: When String is too unstructured but a custom enum is overkill
• Examples: As the standard error type in documentation examples
• Production: When error categories map cleanly to these variants

Example

use ranvier_core::error::RanvierError;

let err = RanvierError::not_found("User 42");
assert_eq!(err.to_string(), "not found: User 42");

Variants

Message(String)

Generic message error

NotFound(String)

Resource not found

Validation(String)

Input validation failure

Internal(String)

Internal / unexpected error

Implementations

impl RanvierError

pub fn message(msg: impl Into<String>) -> Self

Create a generic message error.

pub fn not_found(what: impl Into<String>) -> Self

Create a not-found error.

pub fn validation(msg: impl Into<String>) -> Self

Create a validation error.

pub fn internal(msg: impl Into<String>) -> Self

Create an internal error.

Trait Implementations

impl Clone for RanvierError

fn clone(&self) -> RanvierError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RanvierError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RanvierError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for RanvierError

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

Formats the value using the given formatter.

impl Error for RanvierError

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 From<&str> for RanvierError

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<String> for RanvierError

fn from(s: String) -> Self

Converts to this type from the input type.

impl PartialEq for RanvierError

fn eq(&self, other: &RanvierError) -> 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 RanvierError

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
