Crate wesley_emit_codec 

Language-neutral LE-binary codec plan.

This crate lowers a Wesley L1 IR into a small, target-agnostic description of what the codec does — which values are scalars, enums, nested structs, options, or lists, and in what field order. The Rust and TypeScript emitters consume this one plan and only decide how to spell it in their language, so the structural logic (nullable → option, list → length-prefixed, scalar → primitive, named type → sub-codec) lives in exactly one place and the two backends cannot drift on the wire.

Names in the plan are the source GraphQL names; each backend applies its own casing (rust_field_name, pascalCase, …).

Structs

FieldPlan

One field of a struct, in wire (declaration) order.

Enums

CodecDef

A top-level codec, emitted as an encode_* / decode_* pair.

CodecOp

How to read or write a single value. Recurses for options and lists; a CodecOp::Named defers to another CodecDef’s codec by source name.

ScalarKind

A primitive wire scalar.

StructKind

Which SDL declaration a struct codec came from. Carried so a backend can label the declaration in its own idiom; it does not affect the wire format.

Functions

plan

Lower a Wesley L1 IR and its operations into the codec plan.
