Crate roam_schema 

Schema types for roam RPC service definitions.

Design Philosophy

This crate uses facet::Shape directly for type information rather than defining a parallel type system. This means:

• No TypeDetail — We use &'static Shape from facet instead
• Full type introspection — Shape provides complete type information
• Zero conversion overhead — Types are described by their Shape directly

For type-specific queries (is this a stream? what are the struct fields?), use the facet_core API to inspect the Shape.

Structs

ArgDetail

A single argument in a method signature.

EnumInfo

Information about an enum type.

MethodDetail

A single method in a service definition.

MethodSummary

Summary information about a method (for listings/discovery).

ServiceDetail

A complete service definition with all its methods.

ServiceSummary

Summary information about a service (for listings/discovery).

StructInfo

Information about a struct type.

Enums

MismatchExplanation

Explanation of why a method call mismatched.

ShapeKind

Classification of a Shape for codegen purposes.

VariantKind

Information about an enum variant for codegen.

Functions

classify_shape

Classify a Shape into a ShapeKind for codegen.

classify_variant

Classify an enum variant.

contains_stream

Recursively check if a shape or any of its type parameters contains a stream.

fully_qualified_type_path

Returns the fully qualified type path, e.g. “std::collections::HashMap<K, V>”.

is_bytes

Check if a shape represents bytes (Vec<u8> or &[u8]).

is_rx

Check if a shape represents an Rx (callee→caller) stream.

is_stream

Check if a shape represents any streaming type (Tx or Rx).

is_tx

Check if a shape represents a Tx (caller→callee) stream.
