Enum MachineFingerprint 

pub enum MachineFingerprint {
    Static(String),
    Fn(Arc<dyn Fn() -> BoxFuture<'static, String> + Send + Sync>),
}

User-supplied machine fingerprint source, replacing the native machine id. The value is still hashed before use.

Variants

Static(String)

Used verbatim as the raw machine value.

Fn(Arc<dyn Fn() -> BoxFuture<'static, String> + Send + Sync>)

Awaited once; its result is the raw machine value.

Implementations

impl MachineFingerprint

From an async function.

pub fn from_sync_fn<F>(f: F) -> Self

where F: Fn() -> String + Send + Sync + 'static,
