Struct FieldCoverage 

pub struct FieldCoverage {
    pub offset_bitmaps: Vec<Vec<u8>>,
}

Per-field coverage for a sparse overlay.

Fields

offset_bitmaps: Vec<Vec<u8>>

One entry per field in the overlay’s data_file.fields, in the same order. Each is a 32-bit Roaring bitmap of the physical row offsets covered for that field. An offset present in a field’s bitmap but mapped to a NULL value means the cell is overridden to NULL (distinct from an offset that is absent, which falls through to the base data file).

Trait Implementations

impl Message for FieldCoverage

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,
