Struct Chunk 

#[non_exhaustive]
pub struct Chunk {
    pub length: u64,
    pub owner: u64,
    pub stripe_len: u64,
    pub chunk_type: u64,
    pub num_stripes: u16,
    pub sub_stripes: u16,
    pub stripes: Vec<Stripe>,
}

A parsed btrfs_chunk item: chunk geometry + its physical stripes.

The chunk’s logical start is its item key’s offset (carried alongside in Node::chunk_items), not stored inside the chunk struct.

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.

length: u64

length — the chunk’s logical byte span.

owner: u64

owner — the objectid that owns the chunk (2 = the extent tree).

stripe_len: u64

stripe_len — the stripe unit size.

chunk_type: u64

type — the BTRFS_BLOCK_GROUP_* flag bits (DATA/SYSTEM/METADATA | DUP…).

num_stripes: u16

num_stripes — the number of physical stripes that follow.

sub_stripes: u16

sub_stripes — RAID10 sub-stripe count (1 for single/DUP).

stripes: Vec<Stripe>

The decoded stripes (physical placements).
