Struct FragmentationStats

Help

pub struct FragmentationStats {
    pub extent_size: [u64; 12],
    pub extent_count: [u64; 12],
    pub free_space: [u64; 12],
}

Fields§

§extent_size: [u64; 12]

Histogram of extent size in bytes. Buckets are fixed as 0, <=4kB, <=8kB, … <=2MiB, >2MiB.

§extent_count: [u64; 12]

Histogram of extents per file. Buckets are fixed as 0, <=1, <=2, … <=512, >512.

§free_space: [u64; 12]

Histogram of free space in bytes. Buckets are fixed as 0, <=4kB, <=8kB, … <=2MiB, >2MiB.
