Struct StreamStats 

pub struct StreamStats {
    pub items_buffered: usize,
    pub estimated_memory: usize,
    pub total_rows_yielded: u64,
    pub total_rows_filtered: u64,
}

Stream statistics snapshot

Provides a read-only view of current stream state without consuming items. All values are point-in-time measurements.

Fields

items_buffered: usize

Number of items currently buffered in channel (0-256)

estimated_memory: usize

Estimated memory used by buffered items in bytes

total_rows_yielded: u64

Total rows yielded to consumer so far

total_rows_filtered: u64

Total rows filtered out by Rust predicates

Implementations
