Enum Access 

pub enum Access {
    ResRead(TypeId),
    ResWrite(TypeId),
    CompRead(TypeId),
    CompWrite(TypeId),
}

Describes what a system parameter accesses — used for conflict detection.

Variants

ResRead(TypeId)

Shared read of a resource.

ResWrite(TypeId)

Exclusive write of a resource.

CompRead(TypeId)

Shared read of a component type.

CompWrite(TypeId)

Exclusive write of a component type.

Implementations

impl Access

pub fn conflicts_with(&self, other: &Access) -> bool

Returns true if self and other cannot safely coexist in the same system execution.

Conflict rules:

• Read + Write (same TypeId, same namespace) → conflict
• Write + Write (same TypeId, same namespace) → conflict
• Read + Read → no conflict
• Cross-namespace (Res vs Comp) → no conflict
