Go 1.20 removed the preinstalled `.a` files for the standard library
from the Go distribution.
Installations now build and cache the standard library like
packages in other modules.

are many examples in the sources of the standard library, in packages such as

You can also examine what the compiler emits as assembly code

# Gradle platform architecture

Gradle is arranged into coarse-grained components called "architecture modules" and "platforms".
See [ADR4](standards/0004-use-a-platform-architecture.md) for a definition of these terms.

The diagram below shows the current set of architecture modules and platforms:

### OpenAPI { #openapi }

**FastAPI** genera un "esquema" con toda tu API utilizando el estándar **OpenAPI** para definir APIs.

#### "Esquema" { #schema }

Un "esquema" es una definición o descripción de algo. No el código que lo implementa, sino solo una descripción abstracta.
