A
APIRouter — A class for grouping related routes into modular files. Supports the same decorators as JustAPIApp.
ASGI — Asynchronous Server Gateway Interface, the Python standard for async web servers (used by Starlette/FastAPI/Uvicorn). JustAPI is a native Rust runtime and does not implement ASGI; it runs its own pipeline for maximum throughput.
B
BackgroundTasks — Post-response task execution. Register callables to run after the HTTP response is sent.
Bulkhead — Resilience pattern that limits concurrent requests to prevent resource exhaustion.
C
Circuit Breaker — Resilience pattern that stops calling a failing service when errors exceed a threshold.
CORS — Cross-Origin Resource Sharing. HTTP mechanism for controlling cross-origin requests.
D
Depends — Dependency injection function. Resolves and injects callable results into route handlers.
Dependency Injection — Design pattern where a component's dependencies are provided externally.
G
GIL — Global Interpreter Lock. CPython's mechanism preventing multiple threads from executing Python bytecode simultaneously.
GIL Pool — Subsystem managing GIL-bound worker threads for Python handler execution.
gRPC — High-performance RPC framework using Protocol Buffers.
H
Hyper — Rust HTTP library used by JustAPI for HTTP/1.1 and HTTP/2 parsing.
J
JSON-RPC 2.0 — Lightweight remote procedure call protocol using JSON encoding.
JustAPIApp — The core application class. Register routes, middleware, plugins, and configuration.
M
matchit — Rust radix-trie router library. Provides O(1) path matching.
MCP — Model Context Protocol. Protocol for exposing tools and context to AI agents.
Middleware — Request/response processing layer that runs before and after route handlers.
N
Native Fast Path — Route execution entirely in Rust with native=True. Maximum performance (724k+ RPS).
O
OpenAPI — Standard specification for REST API documentation. JustAPI auto-generates OpenAPI 3.1 specs.
OTel — OpenTelemetry. Observability framework for distributed tracing and metrics.
P
PyO3 — Rust bindings for Python. Used to build the JustAPI Python extension module.
Pydantic — Python library for data validation. JustAPI supports Pydantic v2 models as route schemas.
R
Radix Trie — Tree data structure used by matchit for O(1) route matching.
Rustls — Rust TLS library. Provides TLS 1.2/1.3 support.
S
Schema — JustAPI's built-in validation class. Supports Field constraints and Rust-side validation.
serde_json — Rust JSON serialization library. Used for response serialization.
SSE — Server-Sent Events. HTTP protocol for server-to-client streaming.
sqlx — Rust SQL library with compile-time query checking. Powers JustAPI's database layer.
T
Tokio — Rust async runtime. Powers JustAPI's network I/O and concurrency.
Z
Zero-Copy — Data transfer technique avoiding unnecessary memory copies. Used at the Rust↔Python FFI boundary.
