xrpl_common_stdlib/types/contract_data.rs
1//! `ContractData` — the value type of an escrow's `Data` field.
2//!
3//! An escrow's contract data is a plain fixed-max byte buffer, structurally identical to a
4//! [`StandardBlob`] (`Blob<DEFAULT_BLOB_SIZE>`). It is therefore defined as a transparent alias
5//! rather than a distinct struct: existing `ContractData` references stay valid, and because the
6//! generic ledger-object getters decode any `Blob<N>`, the `Data` field can be read through the
7//! generated `EscrowFields::data()` getter like any other field. The escrow-only *write*
8//! (`set_data`) still lives in `xrpl-escrow-stdlib`.
