Offline mode

[lexi-the-cute]

This needs to be tested. I'm going to spend some time testing to see if it builds in offline mode under normal build circumstances. I still have to figure out how to test it against the script at #21 (comment) for simulating docs.rs

[lexi-the-cute]

So, apparently I somehow managed to partially edit my cargo copy and partially edit my local fork 🤦‍♀️

[lexi-the-cute]

this is the result of testing it locally. not the docs.rs true test cause i need to somehow get it uploaded to crates.io for the way the true test is currently setup

my build scripts calls the set_offline(true) function when the DOCS_RS environment variable is set

use build_info_build::DependencyDepth;
use std::env;

fn main() {
    // Generate build info
    generate_build_info();
}

fn matches_environment_var(key: &str, value: &str) -> bool {
    let environment_var: Result<String, env::VarError> = env::var(key);
    environment_var.is_ok() && environment_var.unwrap() == value
}

fn generate_build_info() {
    let mut depth: DependencyDepth = DependencyDepth::Depth(0);

    // Custom environment variable to speed up writing code
    let rust_analyzer: bool = matches_environment_var("RUST_ANALYZER", "true");
    let docs_rs: bool = env::var("DOCS_RS").is_ok();
    if rust_analyzer || docs_rs {
        depth = DependencyDepth::None;
    }

    let options: build_info_build::BuildScriptOptions =
        build_info_build::build_script().collect_runtime_dependencies(depth);
    if docs_rs {
        options.set_offline(true);
    }
