Struct FileExtentInfo 

pub struct FileExtentInfo {
    pub total_bytes: u64,
    pub shared_bytes: u64,
    pub shared_extents: Vec<(u64, u64)>,
}

Summary of the physical extent usage of a single file.

Fields

total_bytes: u64

Sum of the lengths of all non-inline, non-delalloc extents.

shared_bytes: u64

Bytes covered by extents flagged FIEMAP_EXTENT_SHARED.

shared_extents: Vec<(u64, u64)>

Physical (start, end_exclusive) ranges of every shared extent.

Callers that need to compute a “set shared” total across multiple files should collect these ranges, sort, and merge overlaps.
