Struct VldServerError 

pub struct VldServerError {
    pub message: String,
    pub fields: Vec<FieldError>,
}

Structured validation error for Dioxus server functions.

Serializable and deserializable — can be transmitted from server to client as part of a ServerFnError message or custom error type.

With ServerFnError

#[server]
async fn my_fn(name: String) -> Result<(), ServerFnError> {
    vld_dioxus::validate_args! {
        name => vld::string().min(2),
    }.map_err(|e| ServerFnError::new(e.to_string()))?;
    Ok(())
}

With custom error type

#[derive(Debug, Clone, Serialize, Deserialize)]
enum AppError {
    Validation(VldServerError),
    Server(String),
}

impl FromServerFnError for AppError { /* ... */ }

#[server]
async fn my_fn(name: String) -> Result<(), AppError> {
    vld_dioxus::validate_args! {
        name => vld::string().min(2),
    }.map_err(AppError::Validation)?;
    Ok(())
}

Fields

message: String

Summary message.

fields: Vec<FieldError>

Per-field validation errors.

Implementations

impl VldServerError

pub fn validation(fields: Vec<FieldError>) -> Self

Create a validation error from a list of field errors.

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

Create an internal/serialization error.

pub fn field_error(&self, field: &str) -> Option<&str>

Get the error message for a specific field.

pub fn field_errors(&self, field: &str) -> Vec<&str>

Get all error messages for a specific field.

pub fn has_field_error(&self, field: &str) -> bool

Check if a specific field has errors.

pub fn error_fields(&self) -> Vec<&str>

List all field names that have errors.

pub fn from_json(s: &str) -> Option<Self>

Parse a VldServerError from a JSON string (e.g. from ServerFnError message).

Returns None if the string is not a valid VldServerError JSON.

Trait Implementations

impl Clone for VldServerError

fn clone(&self) -> VldServerError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VldServerError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VldServerError

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for VldServerError

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

Formats the value using the given formatter.

impl Error for VldServerError

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<VldError> for VldServerError

fn from(error: VldError) -> Self

Converts to this type from the input type.

impl PartialEq for VldServerError

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
