Struct csv_pipeline::Headers

pub struct Headers { /* private fields */ }

The headers of a CSV file

Implementations

impl Headers

pub fn new() -> Self

pub fn rename(&mut self, from: &str, to: &str) -> Result<(), RenameError>

Returns Error::MissingColumn if from is non-existant or Error::DuplicateColumn the new name already exists

pub fn push_field(&mut self, name: &str) -> bool

Returns false if the field already exists

pub fn contains(&self, name: &str) -> bool

pub fn get_field<'a>(&self, row: &'a Row, name: &str) -> Option<&'a str>

pub fn get_index(&self, name: &str) -> Option<usize>

pub fn get_row(&self) -> &Row

pub fn from_row(row: Row) -> Result<Self, String>

If a column is duplicated, errors with the column name

Trait Implementations

impl Clone for Headers

fn clone(&self) -> Headers

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Headers

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

Formats the value using the given formatter.

impl From<Headers> for Row

fn from(headers: Headers) -> Row

Converts to this type from the input type.

impl<'a> IntoIterator for &'a Headers

type Item = &'a str

The type of the elements being iterated over.

type IntoIter = StringRecordIter<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> StringRecordIter<'a>

Creates an iterator from a value.

impl PartialEq<Headers> for Headers

fn eq(&self, other: &Headers) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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