Module locator 

Builder for nested field access locators.

Locators encode a path to a nested field (sfields and array indices) in a compact binary format understood by the host. Use it to access fields like Memos[0].MemoType.

Example

use xrpl_wasm_stdlib::core::locator::Locator;
use xrpl_wasm_stdlib::sfield;
let mut l = Locator::new();
l.pack(sfield::Memos);
l.pack(0);
l.pack(sfield::MemoType);

Structs

Locator

A Locator allows a WASM developer located any field in any object (even nested fields) by specifying a slot_num (1 byte); a locator_field_type (1 byte); then one of an sfield (4 bytes) or an index (4 bytes).
