Enum ResolverError 

pub enum ResolverError {
    RuleNotFound(String),
    UnresolvableConflict {
        rule_a: String,
        rule_b: String,
    },
    CyclicDependency(Vec<String>),
    ConfigurationError(String),
    MaxRulesExceeded,
}

Errors that can be returned by RuleConflictResolver operations.

Variants

RuleNotFound(String)

A rule ID was referenced but no such rule exists.

UnresolvableConflict

The conflict between rule_a and rule_b cannot be resolved automatically.

Fields

rule_a: String

First conflicting rule ID.

rule_b: String

Second conflicting rule ID.

CyclicDependency(Vec<String>)

A cyclic dependency was detected among the listed rules.

ConfigurationError(String)

Invalid or inconsistent resolver configuration.

MaxRulesExceeded

The rule set would exceed ResolverConfig::max_rules.

Trait Implementations

impl Clone for ResolverError

fn clone(&self) -> ResolverError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResolverError

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

Formats the value using the given formatter.

impl Display for ResolverError

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

Formats the value using the given formatter.

impl Error for ResolverError

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 ResolverError

fn eq(&self, other: &ResolverError) -> 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.
