Function fuchsia_merkle::hash_block

pub fn hash_block(block: &[u8], offset: usize) -> Hash

Compute the merkle hash of a block of data.

A merkle hash is the SHA-256 hash of a block of data with a small header built from the length of the data, the level of the tree (0 for data blocks), and the offset into the level. The block will be zero filled if its len is less than BLOCK_SIZE, except for when the first data block is completely empty.

Panics

Panics if block.len() exceeds BLOCK_SIZE or if offset is not aligned to BLOCK_SIZE
