Enum ServerFnError 

pub enum ServerFnError {
    Network(String),
    Serialization(String),

Available on crate feature pages only.

Unified error type for server functions

This error type covers all possible error conditions when calling a server function from the client side.

Variants

Network(String)

Network error (connection failed, timeout, etc.)

Serialization(String)

Serialization error (failed to serialize arguments)

Deserialization(String)

Deserialization error (failed to deserialize response)

Server

Server-side error (HTTP 4xx, 5xx)

Fields

status: u16

HTTP status code

message: String

Error message

Application(String)

Application error (custom error from server function)

Implementations

impl ServerFnError

pub fn network(msg: impl Into<String>) -> ServerFnError

Create a network error

pub fn serialization(msg: impl Into<String>) -> ServerFnError

Create a serialization error

pub fn deserialization(msg: impl Into<String>) -> ServerFnError

Create a deserialization error

pub fn server(status: u16, message: impl Into<String>) -> ServerFnError

Create a server error

pub fn application(msg: impl Into<String>) -> ServerFnError

Create an application error

pub fn message(&self) -> &str

Returns the human-readable message without the variant prefix.

Use this when surfacing the error text directly to end users; use to_string() (Display) for the developer-facing form that includes the variant tag.

Examples

use reinhardt_pages::ServerFnError;

let err = ServerFnError::application("Invalid choice_id");
assert_eq!(err.message(), "Invalid choice_id");
assert_eq!(err.to_string(), "Application error: Invalid choice_id");

Trait Implementations

impl Clone for ServerFnError

fn clone(&self) -> ServerFnError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ServerFnError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ServerFnError

fn deserialize<__D>( __deserializer: __D, ) -> Result<ServerFnError, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ServerFnError

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

Formats the value using the given formatter.

impl Error for ServerFnError

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 Serialize for ServerFnError

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
