    version: &str,
) -> Result<bool>

Checks if a specific version of a crate already exists on crates.io.

Examples

use sampo_core::version_exists_on_crates_io;

// Check if serde 1.0.0 exists (it does)
let exists = version_exists_on_crates_io("serde", "1.0.0").unwrap();
assert!(exists);

// Check if a fictional version exists
let exists = version_exists_on_crates_io("serde", "999.999.999").unwrap();
assert!(!exists);
