merge

Git Source

Merges two compact ranges along a given seed node.

Merge folds hashes in from leftRange and rightRange into seed in order to create a combined compact range. The merged range is left + seed + right. leftRange is assumed to start its coverage at index 0.

function merge(
    bytes32[] calldata leftRange,
    bytes32 seed,
    uint256 seedHeight,
    uint256 seedIndex,
    bytes32[] calldata rightRange,
    uint256 rightRangeEnd
) pure returns (bytes32[] calldata left, bytes32 newSeed, bytes32[] calldata right);

Parameters

Name	Type	Description
leftRange	bytes32[]	The left compact range to merge.
seed	bytes32	The seed node to merge along.
seedHeight	uint256	The height of the seed node.
seedIndex	uint256	The index of the seed node.
rightRange	bytes32[]	The right compact range to merge.
rightRangeEnd	uint256	The end of the right range's coverage.

Returns

Name	Type	Description
left	bytes32[]	The left portion of the merged compact range.
newSeed	bytes32	The new seed node of the merged range.
right	bytes32[]	The right portion of the merged compact range.
