Enum DependencyError 

pub enum DependencyError {
    CircularDependency {
        capability_id: String,
        chain: Vec<String>,
    },
    TooManyCapabilities {
        count: usize,
        max: usize,
    },
}

Error type for dependency resolution failures

Variants

CircularDependency

Circular dependency detected in the capability graph

Fields

capability_id: String

The capability where the cycle was detected

chain: Vec<String>

The dependency chain leading to the cycle

TooManyCapabilities

Too many capabilities after resolution

Fields

count: usize

Number of capabilities requested

max: usize

Maximum allowed

Trait Implementations

impl Clone for DependencyError

fn clone(&self) -> DependencyError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DependencyError

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

Formats the value using the given formatter.

impl Display for DependencyError

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

Formats the value using the given formatter.

impl Eq for DependencyError

impl Error for DependencyError

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 DependencyError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
