# `GraphApi.View`
[🔗](https://github.com/keenmate/microsoft_graph/blob/v1.0.0-rc.1/lib/graph_api/view.ex#L1)

Macro for defining view structs that project a subset of fields from a schema module.

Views provide IDE autocomplete, automatic `$select` injection, and compile-time
field validation against the parent schema.

## Usage

    defmodule MyApp.UserSummary do
      use GraphApi.View,
        schema: GraphApi.Schema.User,
        fields: [:id, :display_name, :mail, :job_title]
    end

This generates:

- `defstruct` with only the listed fields
- `from_map/1` — casts via parent schema's `from_map/1`, then takes only view fields
- `to_map/1` — converts back to camelCase via parent schema
- `__select__/0` — returns camelCase field names for auto `$select` injection
- `__schema__/0` — returns the parent schema module
