eQuantic.Validation.Generator

Incremental Roslyn source generator and usage analyzer for eQuantic.Validation. Trimming- and Native AOT-friendly: no reflection, no MakeGenericType, no runtime expression compilation.

<PackageReference Include="eQuantic.Validation.Generator"
                  PrivateAssets="all"
                  OutputItemType="Analyzer"
                  ReferenceOutputAssembly="false" />

Install it in every project that declares models with [GenerateValidator] or fluent validators.

What it generates

1. Reflection-free validators for annotated models:

[GenerateValidator]
public sealed record CreateCustomer(
    [Required, NotWhiteSpace] string Name,
    [Required, Email(Code = "customer.email.invalid")] string Email,
    [Range(18, 120)] int Age);
// → CreateCustomerGeneratedValidator : IValidator<CreateCustomer>, IDescribableValidator

2. Compile-time DI registration — AddGeneratedValidation() is generated internal to the compiling assembly and registers only that assembly's validators as scoped services. Referenced assemblies are never scanned; compose them explicitly with AddValidator<TModel, TValidator>().

builder.Services.AddGeneratedValidation();

3. Pre-compiled fluent accessors — every RuleFor(x => x.Prop) lambda in your Validator<T> subclasses is compiled at build time and registered at module load. The fluent path never pays Expression.Compile() at runtime (validators are scoped, so that cost used to repeat per request) and never runs through the expression interpreter under Native AOT.

Compile-time diagnostics

ID	Severity	Example that triggers it	Fix
`VALGEN001`	Warning	`AddGeneratedValidation()` without the core + DI abstractions packages	reference `eQuantic.Validation`
`VALGEN002`	Error	`[CustomRule("Missing")]` — no such `bool` method	declare `bool Missing(string? value)` on the model
`VALGEN003`	Warning	`[ValidateEach] string Name` — not `IEnumerable<T>`	apply to collections only
`VALGEN004`	Warning	`[Email] int Age` — string rule on non-string	move the rule to a string property
`VALGEN005`	Error	`RuleFor(x => x.Name!.Trim())` — not a member path	`RuleFor(x => x.Name)` and normalize elsewhere
`VALGEN006`	Error	`RuleFor(x => x.Name).WithMessage("...")` — configurator with no rule	add a rule first: `.NotWhiteSpace().WithMessage("...")`
`VALGEN007`	Warning	`validator.Validate(m)` where the validator has unconditional `MustAsync`	call `ValidateAsync`

VALGEN007 is scenario-aware: async rules scoped with .ForScenarios("create") don't flag synchronous validation.
