#[repr(transparent)]
pub struct RowRef([u8]);
Expand description

A contiguous slice of bytes that are row data.

A RowRef is to Row as str is to String.

Tuple Fields§

§0: [u8]

Implementations§

Source§

impl RowRef

Source

pub fn from_slice(row: &[u8]) -> &RowRef

Create a RowRef from a slice of data.

We do not check that the provided slice is valid Row data, will panic on read if the data is invalid.

Source

pub fn unpack(&self) -> Vec<Datum<'_>>

Unpack self into a Vec<Datum> for efficient random access.

Source

pub fn unpack_first(&self) -> Datum<'_>

Return the first Datum in self

Panics if the RowRef is empty.

Source

pub fn iter(&self) -> DatumListIter<'_>

Iterate the Datum elements of the RowRef.

Source

pub fn byte_len(&self) -> usize

Return the byte length of this RowRef.

Source

pub fn data(&self) -> &[u8]

For debugging only.

Source

pub fn is_empty(&self) -> bool

True iff there is no data in this RowRef.

1.0.0 · Source§

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for RowRef

These implementations order first by length, and then by slice contents. This allows many comparisons to complete without dereferencing memory. Warning: These order by the u8 array representation, and NOT by Datum::cmp.
