Struct PreparedGraft 

pub struct PreparedGraft {
    pub base_generation: u64,
    pub write_generation: u64,
    pub root: u32,
    pub rows: u64,
    pub min: Vec<u8>,
    pub max: Vec<u8>,
    pub last_next: u32,
    pub inserted_min: Vec<u8>,
    pub inserted_max: Vec<u8>,
    pub inserted_rows: u64,
}

Durable description of an unreachable, independently verified graft. Persist this beside a resumable build before acknowledging its final sorter watermark. On reopen, Store::publish_existing_candidate checks both generations, re-verifies every reachable candidate page through a fresh handle, reconstructs the standing parent path, and only then flips the root.

Fields

base_generation: u64

write_generation: u64

root: u32

rows: u64

min: Vec<u8>

max: Vec<u8>

last_next: u32

inserted_min: Vec<u8>

Implementations

impl PreparedGraft

pub fn encode(&self) -> Result<Vec<u8>>

pub fn decode(bytes: &[u8]) -> Result<Self>

pub fn write_manifest(&self, path: &Path) -> Result<()>

Durably replace a candidate descriptor. A torn next descriptor remains at .tmp; reopen reads only the last fsynced-and-renamed manifest.

pub fn read_manifest(path: &Path) -> Result<Self>
