Struct RecordBuilder 

pub struct RecordBuilder { /* private fields */ }

Builder for creating LnmpRecords with guaranteed canonical field ordering

This builder accumulates fields and sorts them by FID before creating the final record, ensuring canonical representation regardless of the order in which fields are added.

Implementations

impl RecordBuilder

pub fn new() -> Self

Creates a new empty builder

Example

use lnmp_core::RecordBuilder;

let builder = RecordBuilder::new();

pub fn add_field(self, field: LnmpField) -> Self

Adds a field to the builder

Fields will be automatically sorted by FID when build() is called.

Example

use lnmp_core::{RecordBuilder, LnmpField, LnmpValue};

let record = RecordBuilder::new()
    .add_field(LnmpField { fid: 10, value: LnmpValue::Int(1) })
    .build();

pub fn add_fields(self, fields: impl IntoIterator<Item = LnmpField>) -> Self

Adds multiple fields at once

Example

use lnmp_core::{RecordBuilder, LnmpField, LnmpValue};

let fields = vec![
    LnmpField { fid: 10, value: LnmpValue::Int(1) },
    LnmpField { fid: 20, value: LnmpValue::Int(2) },
];

let record = RecordBuilder::new()
    .add_fields(fields)
    .build();

pub fn build(self) -> LnmpRecord

Builds the record with fields sorted by FID

This consumes the builder and returns an LnmpRecord with fields in canonical order (sorted by field ID).

Example

use lnmp_core::{RecordBuilder, LnmpField, LnmpValue};

let record = RecordBuilder::new()
    .add_field(LnmpField { fid: 23, value: LnmpValue::Int(3) })
    .add_field(LnmpField { fid: 7, value: LnmpValue::Int(1) })
    .build();

// Fields are sorted
assert_eq!(record.fields()[0].fid, 7);
assert_eq!(record.fields()[1].fid, 23);
