Struct SField 

pub struct SField<T: LedgerObjectFieldGetter, const CODE: i32> { /* private fields */ }

A type-safe wrapper for XRPL serialized field codes.

This struct encodes both the field code and the expected type as const generics, allowing the compiler to automatically infer the correct type when calling get_field.

Example

use xrpl_wasm_stdlib::core::ledger_objects::ledger_object;
use xrpl_wasm_stdlib::sfield;

// Type is automatically inferred from the SField constant
let flags = ledger_object::get_field(0, sfield::Flags).unwrap();  // u32
let balance = ledger_object::get_field(0, sfield::Balance).unwrap();  // u64

Implementations

impl<T: LedgerObjectFieldGetter, const CODE: i32> SField<T, CODE>

pub const fn new() -> Self

Creates a new SField constant.

This is a const function that can be used to initialize SField constants.
