Crate xrpl_escrow_stdlib 

xrpl-escrow-stdlib

Smart Escrow entry-point context and host-function wrappers for writing XRPL Smart Escrows in Rust.

This crate is part of the xrpl-wasm-stdlib workspace. It provides EscrowFinishContext, the control surface a Smart Escrow author interacts with, along with safe, scoped access to escrow-unique host functions (e.g., update_data). All unsafe FFI is contained here; user code stays fully safe.

Usage

use xrpl_escrow_stdlib::*;

fn run(ctx: EscrowFinishContext) -> FinishResult {
    let destination = ctx.escrow().fetch_destination()?;
    // ... evaluate conditions ...
    Ok(true)
}

The #[smart_escrow] entry-point macro (in xrpl-macros) constructs the context via EscrowFinishContext::default() and passes it to your function automatically.
