Enum ServerError 

pub enum ServerError {
    InvalidState(String),
    Configuration(String),
    RuntimeNotFound(String),
    Database(String),
    NotInitialized,
    AlreadyInitialized,
}

Represents all possible errors that can occur within the server lifecycle.

ServerError centralizes failures related to server state management, configuration validation, runtime availability, and database interaction. It is designed to provide clear, descriptive messages for logging and error propagation across the framework.

Variants

• InvalidState — The server is in an unexpected or inconsistent state.
• Configuration — The provided server configuration is invalid or incomplete.
• RuntimeNotFound — The Tokio runtime could not be located or accessed.
• Database — A database-related error occurred during server operation.
• NotInitialized — An operation was attempted before the server was initialized.
• AlreadyInitialized — Initialization was attempted more than once.

Usage

This error type is typically used as the unified error for server setup, startup, and runtime operations.

Example

use rust_microservice::ServerError;

fn start_server() -> Result<(), ServerError> {
    // Example failure
    Err(ServerError::NotInitialized)
}

Variants

InvalidState(String)

Configuration(String)

RuntimeNotFound(String)

Database(String)

NotInitialized

AlreadyInitialized

Trait Implementations

impl Debug for ServerError

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

Formats the value using the given formatter.

impl Display for ServerError

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

Formats the value using the given formatter.

impl Error for ServerError

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.
