Struct Records 

pub struct Records { /* private fields */ }

A chunk’s worth of records, as ranges into the buffer they were read from.

One list of fields for all of the records and one list of where each record’s fields end, which is two allocations that are reused from chunk to chunk rather than one per row.

Implementations

impl Records

pub fn clear(&mut self)

No records, with the room the last chunk needed kept.

pub fn len(&self) -> usize

How many whole records have been read.

pub fn is_empty(&self) -> bool

Whether no whole record has been read.

pub fn fields(&self, at: usize) -> &[Span]

The fields of record at, in order.

Panics

If there is no record at.

pub fn field(&self, row: usize, column: usize) -> Option<Span>

Field column of record row, or None when the record is shorter than that.

pub fn shift(&mut self, by: usize)

Moves every range down by by bytes, for a buffer that has just had that many bytes taken off its front.
