Struct ChunkCounts 

pub struct ChunkCounts { /* private fields */ }

Validated item counts within one open chunk.

Implementations

impl ChunkCounts

pub fn new( read: ChunkCount, processed: ChunkCount, written: ChunkCount, filtered: ChunkCount, ) -> Result<Self, ChunkError>

Validates a complete count snapshot.

processed counts items that produced writer input; filtered counts items intentionally producing no output. Their sum cannot exceed read, and written cannot exceed processed.

Errors

Returns a typed overflow or invalid-state classification.

pub const fn read(self) -> ChunkCount

Returns the read count.

pub const fn processed(self) -> ChunkCount

Returns the successfully processed count.

pub const fn written(self) -> ChunkCount

Returns the acknowledged writer-input count.

pub const fn filtered(self) -> ChunkCount

Returns the filtered count.

pub fn checked_add(self, other: Self) -> Result<Self, ChunkError>

Adds two snapshots and revalidates their aggregate invariants.

Errors

Returns a typed overflow or invalid-state classification.
