Struct PackedBatch 

pub struct PackedBatch {
    pub buffer: Bytes,
    pub offsets: Vec<usize>,
    pub lengths: Vec<usize>,
    pub hit_count: usize,
}

A packed copy-out batch result.

The payload bytes are concatenated into a single contiguous buffer to keep Python object creation and allocator churn low while we still return owned data. offsets[index] == usize::MAX marks a miss.

Fields

buffer: Bytes

Concatenated value bytes for all hits.

offsets: Vec<usize>

Start offset for each requested item, or usize::MAX for a miss.

lengths: Vec<usize>

Value length for each requested item.

hit_count: usize

Number of requested keys that were present.

Implementations

impl PackedBatch

pub fn total_bytes(&self) -> usize

Returns the total number of value bytes copied into buffer.

pub fn item_count(&self) -> usize

Returns the number of keys requested in the batch.

pub fn all_hit(&self) -> bool

Returns true when every requested key was present.

Trait Implementations
