feat(blockscout-service-launcher): add base_path of api

[sevenzing]

add base_path: Option<String> to settings that allows paths to start with custom string like /api/v1/charts -> /stats-service/api/1/charts

Summary by CodeRabbit

• New Features

  • Introduced an optional configuration for routing customization that allows users to define a custom path prefix. This enhancement improves the flexibility of HTTP endpoint exposure and enriches server logging, offering a more tailored service experience.

• Chores

  • Upgraded the package version to 0.19.0 and updated the tokio dependency, resulting in improved performance and overall stability of the service.

Walkthrough

The changes update the blockscout-service-launcher package. In the Cargo.toml file, the package version is incremented from 0.18.0 to 0.19.0, and the tokio dependency is updated from version 1 to 1.44. In the launch.rs file, a new variable base_path is cloned from the settings and passed as an additional argument to the http_serve function. The configure_router function in router.rs is modified to accept an optional base_path parameter, allowing for conditional routing based on its presence. Additionally, in settings.rs, a new optional field base_path is added to the HttpServerSettings struct, along with a new BasePath struct that implements validation through the TryFrom<String> trait.

Poem

I'm a rabbit on a coding spree,
Hopping through changes wild and free.
Versions updated, scopes refined,
New paths emerge where routes align.
With ASCII hops and a cheerful cheer,
I nibble on bytes without any fear.
Code fields and functions—oh dear, what a year!

13-13: Good improvement to code safety.

This change replaces unsafe code with a safe alternative. The previous implementation used unsafe { NonZeroU32::new_unchecked(1) } which bypasses runtime checks, while the new implementation uses NonZeroU32::new(1).unwrap() which properly validates that the value is non-zero at compile time. Since this is a constant with a hardcoded value of 1, there's no performance penalty, but you gain the safety guarantees of Rust's type system.

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
