Mojo struct

LaunchAttribute

struct LaunchAttribute

Represents a complete launch attribute with ID and value.

These are CUDA only, and are not supported on any other target.

Fields

• ​id (LaunchAttributeID): The identifier specifying the type of this launch attribute.
• ​value (LaunchAttributeValue): The value associated with this launch attribute.

Implemented traits
