Struct ByteHeadersIndex 

pub struct ByteHeadersIndex { /* private fields */ }

A ByteRecord wrapper for CSV headers that can be used to efficiently find columns by name, position or even both.

Implementations

impl ByteHeadersIndex

pub fn new(record: ByteRecord, has_names: bool) -> Self

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn first_column_index_by_name( &self, name: impl AsRef<[u8]>, ) -> Option<usize>

pub fn find_column_index( &self, indexation: ColumIndexationBy<'_>, ) -> Option<usize>

Trait Implementations

impl AsRef<ByteRecord> for ByteHeadersIndex

fn as_ref(&self) -> &ByteRecord

impl Debug for ByteHeadersIndex

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Index<usize> for ByteHeadersIndex

type Output = [u8]

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.
