Enum ScheduleBuildWarning 

#[non_exhaustive]
pub enum ScheduleBuildWarning {
    HierarchyRedundancy(Vec<(NodeId, NodeId)>),
    Ambiguity(Vec<(SystemKey, SystemKey, Vec<ComponentId>)>),
}

Category of warnings encountered during Schedule::initialize.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

HierarchyRedundancy(Vec<(NodeId, NodeId)>)

The hierarchy of system sets contains redundant edges.

This warning is enabled by default, but can be disabled by setting ScheduleBuildSettings::hierarchy_detection to LogLevel::Ignore or upgraded to a ScheduleBuildError by setting it to LogLevel::Error.

Ambiguity(Vec<(SystemKey, SystemKey, Vec<ComponentId>)>)

Systems with conflicting access have indeterminate run order.

This warning is disabled by default, but can be enabled by setting ScheduleBuildSettings::ambiguity_detection to LogLevel::Warn or upgraded to a ScheduleBuildError by setting it to LogLevel::Error.

Implementations

impl ScheduleBuildWarning

pub fn to_string(&self, graph: &ScheduleGraph, world: &World) -> String

Renders the warning as a human-readable string with node identifiers replaced with their names.

Trait Implementations

impl Debug for ScheduleBuildWarning

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

Formats the value using the given formatter.

impl Display for ScheduleBuildWarning

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

Formats the value using the given formatter.

impl Error for ScheduleBuildWarning

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 From<ScheduleBuildWarning> for ScheduleBuildError

fn from(source: ScheduleBuildWarning) -> ScheduleBuildError

Converts to this type from the input type.
