Struct Stats 

#[non_exhaustive]
pub struct Stats {
    pub entries: u64,
    pub index_bytes: u64,
    pub disk_bytes: u64,
    pub live_bytes: u64,
    pub segments: usize,
    pub open: OpenReport,
    pub last_error: Option<String>,
}

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.

entries: u64

index_bytes: u64

索引堆内存估算值（字节）。

disk_bytes: u64

live_bytes: u64

segments: usize

open: OpenReport

last_error: Option<String>
