Struct CompactionReport 

#[non_exhaustive]
pub struct CompactionReport {
    pub before: usize,
    pub after: usize,
    pub strategy: &'static str,
}

Reports what History::compact_if_needed did when it ran. Returned wrapped in Option: None means compaction was not needed (history fits within max_tokens).

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.

before: usize

Message count before compaction ran.

after: usize

Message count after compaction ran. after < before whenever the strategy actually dropped or replaced messages.

strategy: &'static str

Stable, machine-readable strategy name from CompactionStrategy::name (e.g. "truncate", "summarize"). Used as the strategy field of StreamChunk::HistoryCompacted.

Trait Implementations

impl Clone for CompactionReport

fn clone(&self) -> CompactionReport

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CompactionReport

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for CompactionReport

fn eq(&self, other: &CompactionReport) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
