Struct VarColumnView 

pub struct VarColumnView<'a> {
    pub null_bitmap: &'a [u8],
    pub offsets: &'a [u8],
    pub values: &'a [u8],
    pub record_count: usize,
}

Zero-copy view of a variable-length column sector inside a mapped .nxb buffer.

Fields

null_bitmap: &'a [u8]

offsets: &'a [u8]

(record_count + 1) × 4 bytes, u32 little-endian (NXS; not Arrow i64).

values: &'a [u8]

record_count: usize

Implementations

impl<'a> VarColumnView<'a>

pub fn from_sector(sector: &'a [u8], record_count: usize) -> Result<Self>

pub fn offset_count(&self) -> usize

Number of u32 offset slots (record_count + 1).
