Variants

InvalidWave

A dependency references a wave outside 0..wave_count.

Fields

wave_count: usize

Declared number of waves.

before: usize

Invalid before endpoint.

after: usize

Invalid after endpoint.

SelfDependency

A wave was declared to depend on itself.

Fields

wave: usize

Self-dependent wave index.

Cycle

The dependency graph contains a cycle and cannot be scheduled.

Fields

unscheduled_waves: usize

Number of waves that could not be scheduled.

ByteCountOverflow

Dependency CSR arithmetic overflowed.

Fields

field: &'static str

Field being computed.

StorageReserveFailed

Planner scratch/result storage could not be reserved.

Fields

field: &'static str

Field being reserved.

requested: usize

Number of elements requested.

message: String

Allocator error text.
