Function is_publishable_to_crates_io 

pub fn is_publishable_to_crates_io(manifest_path: &Path) -> Result<bool>

Determines if a crate is publishable to crates.io based on its Cargo.toml manifest.

Checks the publish field in the [package] section according to Cargo’s rules:

• No publish field: publishable (default)
• publish = false: not publishable
• publish = ["registry1", "registry2"]: publishable only if “crates-io” is in the array

Arguments

• manifest_path - Path to the Cargo.toml file to check

Examples

use std::path::Path;
use sampo_core::is_publishable_to_crates_io;

// Check if a crate is publishable
let publishable = is_publishable_to_crates_io(Path::new("./Cargo.toml")).unwrap();
if publishable {
    println!("This crate can be published to crates.io");
}

Errors

Returns an error if:

• The manifest file cannot be read
• The TOML is malformed
• The manifest has no [package] section (returns Ok(false))
