Struct GenericRecordBuilder 

pub struct GenericRecordBuilder<T: MarcRecord> { /* private fields */ }

Generic builder for constructing MARC records of any type.

This builder uses the MarcRecord trait to provide a unified interface for building any MARC record type (bibliographic, authority, or holdings). It accepts a function to create a new record and provides fluent methods for adding control fields and data fields.

Examples

use mrrc::{GenericRecordBuilder, Record, AuthorityRecord, Leader, Field};

// Build a bibliographic Record
let record = GenericRecordBuilder::new(Record::new(Leader::default()))
    .control_field("001", "12345")
    .control_field("003", "OCoLC")
    .build();

// Build an AuthorityRecord - same interface!
let auth = GenericRecordBuilder::new(AuthorityRecord::new(Leader::default()))
    .control_field("001", "auth001")
    .control_field("003", "DLC")
    .build();

Implementations

impl<T: MarcRecord> GenericRecordBuilder<T>

pub fn new(record: T) -> Self

Create a new builder with an existing record.

Examples

use mrrc::{GenericRecordBuilder, Record, Leader};

let record = Record::new(Leader::default());
let builder = GenericRecordBuilder::new(record);

pub fn control_field( self, tag: impl Into<String>, value: impl Into<String>, ) -> Self

Add or replace a control field (000-009).

Examples

use mrrc::{GenericRecordBuilder, Record, Leader};

let builder = GenericRecordBuilder::new(Record::new(Leader::default()))
    .control_field("001", "12345")
    .control_field("003", "OCoLC");

pub fn record_mut(&mut self) -> &mut T

Get a mutable reference to the underlying record.

This allows modifying the record directly before building it. Useful for accessing record-type-specific methods.

Examples

use mrrc::{GenericRecordBuilder, Record, Leader, Field};

let field = Field::new("245".to_string(), '1', '0');
let mut builder = GenericRecordBuilder::new(Record::new(Leader::default()))
    .control_field("001", "12345");
builder.record_mut().add_field(field);

pub fn record(&self) -> &T

Get a reference to the underlying record.

pub fn build(self) -> T

Build and return the record.

Examples

use mrrc::{GenericRecordBuilder, Record, Leader};

let record = GenericRecordBuilder::new(Record::new(Leader::default()))
    .control_field("001", "12345")
    .build();
