Struct FileExtent 

#[non_exhaustive]
pub struct FileExtent {
    pub logical_offset: u64,
    pub len: u64,
    pub phys_block_num: u64,
    pub crypto_id: u64,
}

One file extent (a j_file_extent_val_t plus its logical offset).

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.

logical_offset: u64

Logical offset within the file (from the record key).

len: u64

Length in bytes (len_and_flags & J_FILE_EXTENT_LEN_MASK).

phys_block_num: u64

Starting physical block (0 = sparse hole).

crypto_id: u64

crypto_id — the AES-XTS tweak of this extent’s first block on an encrypted volume. Zero means the data is not encrypted.
