Enum GraphError 

pub enum GraphError {
    DuplicateModule {
        name: &'static str,
    },
    UnknownImport {
        module: &'static str,
        unknown_import: &'static str,
    },
    CircularDependency {
        cycle: Vec<&'static str>,
    },
}

Available on crate feature dx only.

A typed error from application-graph validation.

Variants

DuplicateModule

Two modules share the same name.

Fields

name: &'static str

UnknownImport

A module imports a module that is not registered in the application.

Fields

module: &'static str

unknown_import: &'static str

CircularDependency

A circular dependency exists among modules. cycle lists the module names in cycle order (e.g. [A, B, C, A]).

Fields

cycle: Vec<&'static str>

Trait Implementations

impl Clone for GraphError

fn clone(&self) -> GraphError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GraphError

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

Formats the value using the given formatter.

impl Display for GraphError

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

Formats the value using the given formatter.

impl Eq for GraphError

impl Error for GraphError

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 PartialEq for GraphError

fn eq(&self, other: &GraphError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
