Statistics collected by walking all blocks of a single B-tree.

Fields

total_nodes: u64

Total number of tree blocks (nodes and leaves).

total_bytes: u64

Total bytes occupied by tree blocks (total_nodes × nodesize).

total_inline: u64

Total bytes of inline file data (non-zero only when find_inline is true).

total_seeks: u64

Number of non-contiguous jumps between sibling block addresses.

forward_seeks: u64

Seeks where the next sibling is at a higher address.

backward_seeks: u64

Seeks where the next sibling is at a lower address.

total_seek_len: u64

Sum of all seek distances in bytes.

max_seek_len: u64

Largest single seek distance in bytes.

total_clusters: u64

Number of contiguous block runs (clusters) counted between seeks.

total_cluster_size: u64

Sum of all cluster sizes in bytes.

min_cluster_size: u64

Smallest cluster size in bytes (u64::MAX if no seeks occurred).

max_cluster_size: u64

Largest cluster size in bytes (initialised to nodesize).

lowest_bytenr: u64

Lowest block bytenr seen during the walk.

highest_bytenr: u64

Highest block bytenr seen during the walk.

node_counts: Vec<u64>

Number of blocks at each level: index 0 = leaves, higher = internal.

levels: u8

Tree height (number of levels, root level + 1).

Trait Implementations
