Crate deluxe_core 

Deluxe Core

Core functions and traits shared between deluxe and deluxe_macros.

This crate is used by deluxe_macros to parse its own attributes. Code generated by its derive macros also references items from this crate re-exported into deluxe. The functions in parse_helpers are used internally by the derive macros, but can also be used for convenience when manually implementing any of the parsing traits.

See the documentation for the deluxe crate for a high-level overview of how Deluxe works.

Modules

parse_helpers

Utility functions for parse trait implementations.

validations

Additional helper functions for validating after parsing.

with

Custom parsing helpers for #[deluxe(with = ...)].

Macros

all_or_none

Appends an error if some attributes are present, but not all of them, automatically casting and stringifying field names.

define_with_collection

Generates a module for parsing a collection using `#[deluxe(with = …)].

define_with_map

Generates a module for parsing a map collection using `#[deluxe(with = …)].

define_with_optional

Generates a module for parsing an optional value using `#[deluxe(with = …)].

only_one

Appends an error if more than one given attribute is present, automatically casting and stringifying field names.

parse_named_meta_item_with

Parses a ParseMetaItem following a name, using a custom parse module.

Structs

Errors

A wrapper for a list of errors. Can be empty.

ErrorsIntoIter

An iterator containing all the errors in an Errors.

Flag

A value for a boolean named field that can only be a name (set) or omitted (unset).

Span

A region of source code, along with macro expansion information.

SpannedValue

A wrapper for adding a Span to an arbitrary value.

Enums

ParseMode

The context a meta item parser is operating in.

Traits

ContainerFrom

Converts a HasAttributes type to a stored container value.

ExtractAttributes

Extracts a structure out of a syn::Attribute list.

HasAttributes

Trait for a syn type containing a list of attributes.

ParseAttributes

Parses a structure out of a syn::Attribute list.

ParseMetaAppend

Parses a meta item for a structure with named fields that concatenates all matching items.

ParseMetaFlatNamed

Parses a meta item for a structure with named fields.

ParseMetaFlatUnnamed

Parses a meta item for a structure with unnamed fields.

ParseMetaItem

Base trait for parsing a single field out of syn::parse::ParseStream.

ParseMetaRest

Parses a meta item for a structure with named fields that consumes all fields.

ToKeyString

A trait for converting an attribute key to a string.

Type Aliases

Error

The error type for parsers.

Result
