Enum KeyValueData

Source
pub enum KeyValueData<'h, B: SplitByteSlice> {
    Small(&'h [u8]),
    Big(BigDataSlices<'h, B>),
}
Expand description

Zero-copy representation of raw Key Value data, returned by KeyValue::data.

Variants§

§

Small(&'h [u8])

The data fits into a single cell. Contains the contiguous range of data bytes.

§

Big(BigDataSlices<'h, B>)

The data is big enough to require more than one cell. Contains an iterator that returns the data byte slice for each cell.
