Struct LiveCheckpoint 

#[non_exhaustive]
pub struct LiveCheckpoint {
    pub superblock_paddr: u64,
    pub xid: u64,
    pub mappings: Vec<CheckpointMapping>,
}

Resolution of the live superblock from the checkpoint ring.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

superblock_paddr: u64

Block address of the chosen (highest-valid-xid) NXSB.

xid: u64

Its transaction id.

mappings: Vec<CheckpointMapping>

Ephemeral oid → paddr mappings from the checkpoint map.
