Enum ContainerError 

pub enum ContainerError {
    NotRegistered(&'static str),
    TypeMismatch(&'static str),
    MissingRouteParam(&'static str),
    ModelNotFound,
}

Errors returned by Container operations and Axum extractors.

Variants

NotRegistered(&'static str)

The requested type was never registered with bind() or singleton().

TypeMismatch(&'static str)

Internal type-map downcast failed — indicates a container bug, not user error.

MissingRouteParam(&'static str)

A required route path parameter was absent.

ModelNotFound

Route model binding found no record matching the route key.

Trait Implementations

impl Debug for ContainerError

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

Formats the value using the given formatter.

impl Display for ContainerError

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

Formats the value using the given formatter.

impl Error for ContainerError

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.
