Structs
Generation
Structure representing a biomapper generation as an element of a doubly linked list.
Pointer of Generation is a number of block that contains a 'generation change' transaction.
Fields
| Name | Type | Description |
|---|---|---|
| generation | bytes32 | A salted hash of some deployment data. Deprecated, do not use. |
| prevPtr | uint256 | Block number of the previous generation. 0 for the oldest generation. |
| nextPtr | uint256 | Block number of the next generation. 0 for the current generation. |
struct Generation {
bytes32 generation;
uint256 prevPtr;
uint256 nextPtr;
}
Biomapping
Structure representing a biomapping as an element of a doubly linked list.
Pointer of Biomapping is a number of block that contains a 'prove uniqueness' transaction.
Fields
| Name | Type | Description |
|---|---|---|
| generationPtr | uint256 | Pointer to the generation that has this biomapping. |
| prevPtr | uint256 | Block number of the previous biomapping. 0 for the oldest biomapping. |
| nextPtr | uint256 | Block number of the next biomapping. 0 for the current biomapping. |
struct Biomapping {
uint256 generationPtr;
uint256 prevPtr;
uint256 nextPtr;
