Struct SnapshotHeader 

pub struct SnapshotHeader {
    pub format_version: u8,
    pub sequence_no: u64,
    pub state_root: B256,
    pub sealed_at_ts: u64,
    pub body_len: u64,
}

Lightweight metadata for a sealed snapshot — no body allocation.

Fields

format_version: u8

On-disk format version. Current: [SNAPSHOT_FORMAT_V1].

sequence_no: u64

State-tree sequence number at which this snapshot was taken.

state_root: B256

State root hash of the unified JMT at sequence_no.

sealed_at_ts: u64

UNIX timestamp (seconds) when the snapshot was sealed.

body_len: u64

Size of the serialized body in bytes.

Trait Implementations

impl Clone for SnapshotHeader

fn clone(&self) -> SnapshotHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SnapshotHeader

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SnapshotHeader

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SnapshotHeader

fn eq(&self, other: &SnapshotHeader) -> 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.

impl Serialize for SnapshotHeader

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
