Enum FileExtentBody 

pub enum FileExtentBody {
    Inline {
        inline_size: usize,
    },
    Regular {
        disk_bytenr: u64,
        disk_num_bytes: u64,
        offset: u64,
        num_bytes: u64,
    },
}

Body of a file extent: either inline data or a reference to a disk extent.

Variants

Inline

Data is stored directly in the tree leaf (small files/tails).

Fields

inline_size: usize

Number of bytes of inline data following the extent header.

Regular

Data is stored in a separate disk extent.

Fields

disk_bytenr: u64

Logical byte address of the extent on disk (0 = hole/sparse).

disk_num_bytes: u64

Size of the on-disk extent in bytes (compressed size if compressed).

offset: u64

Byte offset into the extent where this file range starts.

num_bytes: u64

Number of logical file bytes this extent covers.
