Class ScalarValueModelBinderProvider

Namespace

Trellis.Asp.ModelBinding

Assembly

Trellis.Asp.dll

Detects scalar value types and Maybe<T> wrapping scalar value types, and provides model binders for them.

public class ScalarValueModelBinderProvider : IModelBinderProvider

Inheritance

Examples

Registration in Program.cs:

builder.Services
    .AddControllers()
    .AddScalarValueValidation();

Remarks

This provider checks if a model type implements IScalarValue<TSelf, TPrimitive> or is Maybe<T> where T implements IScalarValue<TSelf, TPrimitive>, and creates appropriate model binders.

Register this provider using AddScalarValueValidation() extension method on IMvcBuilder.

Methods

GetBinder(ModelBinderProviderContext)

Returns a model binder for scalar value types or Maybe<T> wrapping scalar value types, or null for other types.

public IModelBinder? GetBinder(ModelBinderProviderContext context)

Parameters

context ModelBinderProviderContext

The model binder provider context.

Returns

IModelBinder

A model binder for the type, or null if not applicable.

Remarks

This method uses reflection to detect value object types and create binders dynamically. It is not compatible with Native AOT scenarios.
