Struct SnapshotComplete 

pub struct SnapshotComplete {
    pub root_hash: [u8; 32],
    pub total_entities: usize,
    pub total_pages: usize,
    pub uncompressed_size: u64,
    pub compressed_size: Option<u64>,
    pub dag_heads: Vec<[u8; 32]>,
}

Completion marker for snapshot transfer.

Sent after all pages have been transferred. Contains verification information for Invariant I7.

Fields

root_hash: [u8; 32]

Root hash of the complete snapshot. INVARIANT I7: MUST be verified before applying any entities.

total_entities: usize

Total number of entities transferred.

total_pages: usize

Total number of pages transferred.

uncompressed_size: u64

Uncompressed size in bytes.

compressed_size: Option<u64>

Compressed size in bytes (if compression was used).

dag_heads: Vec<[u8; 32]>

DAG heads at the time of snapshot. Used to create checkpoint delta after apply.

Implementations

impl SnapshotComplete

pub fn new( root_hash: [u8; 32], total_entities: usize, total_pages: usize, uncompressed_size: u64, ) -> Self

Create a new snapshot completion marker.

pub fn with_compressed_size(self, size: u64) -> Self

Set compressed size.

pub fn with_dag_heads(self, heads: Vec<[u8; 32]>) -> Self

Set DAG heads.

pub fn compression_ratio(&self) -> Option<f64>

Calculate compression ratio (if compression was used).

pub fn is_valid(&self) -> bool

Check if completion is within valid bounds.

Trait Implementations

impl BorshDeserialize for SnapshotComplete

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for SnapshotComplete

fn serialize<__W: Write>(&self, writer: &mut __W) -> Result<(), Error>

impl Clone for SnapshotComplete

fn clone(&self) -> SnapshotComplete

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SnapshotComplete

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SnapshotComplete

fn eq(&self, other: &SnapshotComplete) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
