Struct marc::record::Controlfield

pub struct Controlfield { /* private fields */ }

MARC Control Field whose tag value is < “010”

Implementations

impl Controlfield

pub fn to_breaker(&self) -> String

impl Controlfield

pub fn new( tag: impl Into<String>, content: impl Into<String>, ) -> Result<Self, String>

Create a Controlfield with the provided tag and content.

• tag - Must have the correct byte count.

Examples

let control_field = marc::Controlfield::new("008", "12345").unwrap();
assert_eq!(control_field.tag(), "008");

let control_field = marc::Controlfield::new("010", "12345");

assert_eq!(control_field.is_err(), true);
assert_eq!(control_field.unwrap_err(), "Invalid Controlfield tag: 010");

pub fn tag(&self) -> &str

Get the tag

Examples

use marc::Controlfield;

let control_field = Controlfield::new("008", "12345").unwrap();
assert_eq!(control_field.tag(), "008");

pub fn content(&self) -> &str

Get the content

Examples

use marc::Controlfield;

let control_field = Controlfield::new("008", "12345").unwrap();
assert_eq!(control_field.content(), "12345");

pub fn set_content(&mut self, content: impl Into<String>)

Set the Controlfield content.

Examples

use marc::Controlfield;

let mut control_field = Controlfield::new("008", "12345").unwrap();
control_field.set_content("6789");
assert_eq!(control_field.content(), "6789");

Trait Implementations

impl Clone for Controlfield

fn clone(&self) -> Controlfield

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Controlfield

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

Formats the value using the given formatter.

impl PartialEq for Controlfield

fn eq(&self, other: &Controlfield) -> 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.
