You create custom Rust lints using the Dylint framework, which supports defining both AST-level (EarlyLintPass) and type-checked (LateLintPass) lints to enforce project-specific code conventions.

Dylint is a framework for building custom Rust lint libraries. It allows you to enforce team conventions by creating reusable lint rules that integrate into your standard Rust development workflow.

Yes, writing custom lints with Dylint integrates directly with rustc internals and leverages clippy_utils to generate diagnostics for both AST-level and type-checked lint passes.

You can write a custom Rust lint using Dylint to detect unwrap() calls and enforce that they are replaced with expect() messages, ensuring explicit error handling across your codebase.

EarlyLintPass operates on the AST level before type checking, while LateLintPass operates on type-checked code, allowing custom Rust lints to analyze fully resolved types and expressions.

Yes, this approach to writing custom Rust lints provides structured development with templates and testing utilities to validate lint behavior before integrating them into your workflow.
