class SuperblockVerifier

Defined at line 32 of file ../../src/devices/block/drivers/block-verity/superblock-verifier.h

`SuperblockVerifier` encapsulates asynchronously loading and verifying that a

superblock hashes to the `expected_superblock_hash` provided to the

constructor, and also verifies that the configuration expressed therein is

supported by this version of the driver.

Example:

SuperblockVerifier verifier(std::move(info), superblock_hash);

if (rc != verifier.StartVerifying(this, OnSuperblockVerificationComplete)) {

return rc;

}

/* OnSuperblockVerificationComplete does something useful with the superblock */

Public Methods

void SuperblockVerifier (DeviceInfo info, const std::array<uint8_t, kHashOutputSize> & expected_superblock_hash)

zx_status_t StartVerifying (void * cookie, SuperblockVerifierCallback callback)

Load the superblock from the device specified in `info_` and verify its hash

matches `expected_superblock_hash_`. If it does, calls `callback` with

ZX_OK and a borrowed pointer to a superblock struct in `superblock` which

will cease to be valid at the end of the callback. If not, calls `callback`

with a non-ZX_OK status and a null pointer for `superblock`.
