## What it is
EASTL is Electronic Arts' C++ Standard Template Library, providing containers, algorithms, and iterators with an emphasis on high performance. It is a mature, extensively used replacement or supplement to the standard STL, suitable for runtime and tool development across many platforms.

## Use cases
- replace std containers with faster alternatives in a game engine
- high-performance C++ containers for embedded or console platforms
- STL-compatible containers with better allocator control
- template library for runtime and tool development in C++
- containers and algorithms tuned for shipping game code

## When to choose
- you need maximum performance and control over memory allocation in C++
- you target game consoles, embedded systems, or platforms with weak STL implementations
- you want STL-familiar containers with extra features like fixed-size containers

## When to avoid
- your project is simple and the standard STL is sufficient
- you need strict standard-library conformance or portability with std interfaces
- you want a small dependency-free codebase

## Facets
- artifact type: library
- maturity: stable
- function: serialization, developer-tools
- domain: performance, cross-platform
- platform: cpp, cross-platform, embedded, windows
- tags: stl, containers, algorithms, iterators, templates, high-performance, header-only, game-engines, game-development, linux, macos
