Struct Error 

pub struct Error { /* private fields */ }

A structured HTTP error with status, code, message, and flexible details.

Implementations

impl Error

pub fn new( status: StatusCode, code: impl Into<String>, message: impl Into<String>, ) -> Self

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

Convenience: creates an InternalServerError with a custom message.

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

Creates an InternalServerError with code "panic" for caught panics.

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

pub fn detail(self, key: impl Into<String>, value: Value) -> Self

pub fn with_source(self, err: impl Error + Send + Sync + 'static) -> Self

pub fn status_code(&self) -> StatusCode

pub fn code(&self) -> &str

pub fn message_str(&self) -> &str

pub fn details(&self) -> &HashMap<String, Value>

pub fn default_response(&self) -> Response

Renders the default JSON response for this error. Custom error handlers can call this to delegate back to the default rendering.

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
