Implementations

impl VariantMerkleTree

pub fn empty(kind: MerkleTreeKind, sector_sz: usize) -> VariantMerkleTree

Trait Implementations

impl<'de> Deserialize<'de> for VariantMerkleTree

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'_enum> From<&'_enum VariantMerkleTree> for MerkleTreeKind

fn from(val: &'_enum VariantMerkleTree) -> MerkleTreeKind

Converts to this type from the input type.

impl From<VariantMerkleTree> for MerkleTreeKind

fn from(val: VariantMerkleTree) -> MerkleTreeKind

Converts to this type from the input type.

impl MerkleTree for VariantMerkleTree

fn assert_root_contains(&mut self, hash_data: Option<&[u8]>) -> Result<()>

Checks that the root node contains the given hash data. If it does then Ok(()) is returned. If it doesn’t, then Err(Error::HashCmpFailure) is returned.

fn root_hash(&self) -> Result<&[u8]>

Returns the hash data stored in the root node of the tree. An error is returned if and only if the tree is empty.

fn verify(&self, offset: usize, data: &[u8]) -> Result<()>

Verifies that the given data stored from the given offset into the protected data, has not been modified.

fn write(&mut self, offset: usize, data: &[u8]) -> Result<()>

Hashes the given data, adds a new node to the tree with its hash and updates the hashes of all parent nodes.

impl Sectored for VariantMerkleTree

fn sector_sz(&self) -> usize

Returns the size of the sector for this stream.

fn sector_sz64(&self) -> u64

Returns the sector size as a u64.

fn assert_sector_sz(&self, actual: usize) -> Result<()>

Returns Err(Error::IncorrectSize) if the given size is not equal to the sector size.

fn assert_at_least_sector_sz(&self, actual: usize) -> Result<()>

Returns Err(Error::IncorrectSize) if the given size is less than the sector size.

fn offset_at(&self, index: u64) -> u64

Returns the offset (in bytes) from the beginning of this stream that the given 0-based sector index corresponds to.

impl Serialize for VariantMerkleTree

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
