Struct DbStat 

#[non_exhaustive]
pub struct DbStat {
    pub format_major: u16,
    pub format_minor: u16,
    pub page_size: u16,
    pub page_count: u64,
    pub file_size_bytes: u64,
    pub collections: Vec<CollectionStat>,
}

One-shot snapshot of a database’s header + catalog summary.

Returned by Db::stat. CLI-facing — may evolve pre-1.0; user code should reach for the typed Db::iter_all / Db::read_transaction(|tx| tx.collection::<T>()) APIs instead.

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.

format_major: u16

Format major version from page 0.

format_minor: u16

Format minor version from page 0.

page_size: u16

On-disk page size in bytes.

page_count: u64

Total number of pages in the database, including page 0.

file_size_bytes: u64

Logical file size in bytes (page_count * page_size). For file-backed pagers this equals the on-disk size; for memory pagers it is the in-memory backing buffer length.

collections: Vec<CollectionStat>

One entry per registered collection. Order matches the catalog B-tree’s natural sort (by name).
