Struct datafusion::common::arrow::array::ByteView

#[repr(C)]
pub struct ByteView {
    pub length: u32,
    pub prefix: u32,
    pub buffer_index: u32,
    pub offset: u32,
}

Helper to access views of GenericByteViewArray (StringViewArray and BinaryViewArray) where the length is greater than 12 bytes.

See the documentation on GenericByteViewArray for more information on the layout of the views.

The length of the string/bytes.

prefix: u32

First 4 bytes of string/bytes data.

buffer_index: u32

The buffer index.

offset: u32

The offset into the buffer.
