Crate server_less_parse 

Shared parsing utilities for server-less proc macros.

This crate provides common types and functions for extracting method information from impl blocks.

Internal API. This crate exists to support the server-less proc macros and is published only because path dependencies are disallowed. Its surface is typed in terms of syn / proc-macro2 and carries no stability guarantees; depend on the server-less facade instead.

Structs

GroupRegistry

Registry of declared method groups from #[server(groups(...))].

MethodInfo

Parsed method information with full syn AST types.

ParamInfo

Parsed parameter information

ParsedParamAttrs

Parsed result of #[param(...)] attributes.

PartitionedMethods

Categorized methods for code generation.

ReturnInfo

Parsed return type information

Enums

HttpMethod

Compile-time HTTP method enum used by proc macros during code generation.

ParamLocation

Parameter location for HTTP requests

Functions

did_you_mean

Return the closest candidate to input within edit distance ≤ 2, or None.

extract_docs

Extract doc comments from attributes

extract_groups

Extract the group registry from #[server(groups(...))] on an impl block.

extract_iterator_item

Check if a type is impl Iterator<Item=T> and extract T

extract_map_type

Check if a type is HashMap<K, V> or BTreeMap<K, V> and extract K and V

extract_methods

Extract all methods from an impl block

extract_option_type

Check if a type is Option<T> and extract T

extract_result_types

Check if a type is Result<T, E> and extract T and E

extract_stream_item

Check if a type is impl Stream<Item=T> and extract T

extract_vec_type

Check if a type is Vec<T> and extract T

get_impl_name

Get the struct name from an impl block

ident_str

Convert an identifier to a string, stripping the r# prefix for raw identifiers.

is_bool_type

Check if a type is bool

is_id_param

Check if a parameter name looks like an ID

is_option_type

Check if a type is Option<T>

is_unit_type

Check if a type is ()

levenshtein

Compute Levenshtein edit distance between two strings.

parse_param_attrs

Parse #[param(…)] attributes from a parameter

parse_params

Parse function parameters (excluding self)

parse_return_type

Parse return type information

partition_methods

Partition methods into leaf commands, static mounts, and slug mounts.

resolve_method_group

Resolve a method’s group against the registry.

unwrap_option_type

If ty is Option<T>, returns Some(&T). Otherwise returns None.

unwrap_result_ok_type

If ty is Result<T, E>, returns Some(&T). Otherwise returns None.

unwrap_vec_type

If ty is Vec<T>, returns Some(&T). Otherwise returns None.
