Implementations

impl LicenseManager

pub fn check_cpu_core_limit( &self, cpu_core_count: u64, ) -> Result<(), CpuCoreLimitExceeded>

Check if the given CPU core count exceeds the limit as per the license key.

impl LicenseManager

pub(crate) fn new() -> Self

Create a new license manager with the default license.

pub fn get() -> &'static Self

Get the singleton instance of the license manager.

pub fn refresh(&self, license_key: LicenseKeyRef<'_>)

Refresh the license with the given license key.

pub fn license(&self) -> Result<License, LicenseKeyError>

Get the current license if it is valid.

Since the license can expire, the returned license should not be cached by the caller.

Prefer calling crate::Feature::check_available to check the availability of a feature, other than directly calling this method and checking the content of the license.
