Two identifiers, two different jobs. DefId names a definition across the whole compiler pipeline and across crates. HirId points to a node in the syntax tree of the current crate. Mixing them up is the first stumbling block when reading rustc source code.

Most comparisons of gRPC streaming vs unary stop at the API surface. This one goes to the wire — HTTP/2 frames, protobuf framing, peak memory, and latency to first byte.

How I built a custom code execution engine backed by a Rust/Axum microservice, embedded directly in blog articles. Covers the security model, subprocess isolation with setrlimit, HMAC request signing, and the tradeoffs behind every decision.

Today I redeployed my blog and 4 out of 6 project images were broken. Here is the story of how I tracked down the issue.
