Struct CircularDependencyError 

pub struct CircularDependencyError {
    pub cycle: Vec<String>,
}

Error returned when a circular dependency is detected.

This error contains the full cycle path showing which types form the cycle. For example, if DbPool depends on UserService which depends on DbPool, the cycle would be: ["DbPool", "UserService", "DbPool"].

Example

Circular dependency detected: DbPool -> UserService -> DbPool

Fields

cycle: Vec<String>

The names of the types forming the cycle, in resolution order. The first and last element are the same type (completing the cycle).

Implementations

impl CircularDependencyError

pub fn new(cycle: Vec<String>) -> Self

Create a new circular dependency error with the given cycle path.

pub fn cycle_path(&self) -> String

Get a human-readable representation of the cycle.

Trait Implementations

impl Clone for CircularDependencyError

fn clone(&self) -> CircularDependencyError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CircularDependencyError

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

Formats the value using the given formatter.

impl Display for CircularDependencyError

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

Formats the value using the given formatter.

impl Error for CircularDependencyError

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 IntoResponse for CircularDependencyError

fn into_response(self) -> Response
