Enum LClusterEntry 

pub enum LClusterEntry {
    Head(LClusterHead),
    NonHead {
        delta0: u16,
    },
}

An entry describing a single logical cluster, which most often corresponds with a single logical, uncompressed block. These entries build a map for where to find the data in the compressed physical blocks.

Variants

Head(LClusterHead)

A head cluster. See LClusterHead.

NonHead

A nonhead cluster. These are blocks of data contained within the extent described by the most recent head lcluster.

Fields

delta0: u16

The distance back to the most recent head lcluster.

Implementations

impl LClusterEntry

pub fn read_full_entry( reader: &dyn Reader, offset: u64, ) -> Result<Self, ErofsError>

Parse a single lcluster entry. This is for the CompressedFull data layout, for the CompressedCompact data layout, see [read_compact_lcluster_entry].
