- Line 36: Replace the unwrap on args.encode() in update_verifier_registry()
with explicit error propagation by changing the builder to return
Result<Instruction, ...> and forwarding the encoding error; only preserve a
non-fallible return if a concrete invariant is enforced that guarantees encoding
cannot fail.

wheels crate crates.io variable_offset_layout Encodable encode
💡 Result:
There is no widely known Rust crate named "wheels" that features "variable_offset_layout" or the "Encodable::encode" pattern as its core definition. The terminology you are inquiring about appears to stem from separate, unrelated Rust libraries: 1. Encoding and Serialization: The "Encodable" trait and its "encode" method are core components of the "encode" crate [1][2][3]. This crate is a toolbox for building encoders and serializers, drawing inspiration from parsing libraries like "nom" and "winnow" [2][3]. Its Encodable trait is defined as: fn encode(&self, encoder: &mut E) -> Result<, Self::Error>; 2. Memory and Data Layout: The term "variable_offset_layout" is not a standard crate name, but the concept of explicit memory and field layout in Rust is addressed by several specialized crates, including: - "memory-layout" [4]: Allows defining struct layouts similar to C#'s [StructLayout(LayoutKind.Explicit)] [4]. - "struct_layout" [5]: Provides a similar mechanism with a focus on internal arrays and specific offset annotations [5]. - "binary_layout" [6]: Provides a type-safe, zero-copy way to access binary data structures [6]. 3. Crates named "wheel": Several unrelated crates exist with "wheel" in their name, such as "wheel-rs" (a general utility library) [7][8], "uwheel" (for stream aggregation) [9], "logs-wheel" (for rolling log files) [10], and "bitwheel" (for high-performance timers) [11]. None of these are primarily associated with the encoding or layout features mentioned. If you are following a specific tutorial or project, you may be conflating these distinct libraries. To use the encoding functionality, you should refer to the "encode" crate documentation [2], and for explicit memory layout, you should investigate "memory-layout" or "binary_layout" [4][6].

Replace the fallible encoding unwrap.
args.encode() can return an error, and update_verifier_registry() currently panics by using .unwrap(). Return a Result<Instruction, ...> from this builder, or document and enforce an invariant that makes encoding failure impossible.
