nebius.aio.token.token.NamedBearer

class documentation

class NamedBearer(Bearer): (source)

Constructor: NamedBearer(wrapped, name)

View In Hierarchy

Simple bearer wrapper that attaches a static name to another bearer.

This may be used in some wrapper providers to cache the results of the shared receiver, or to report diagnostics.

This name should reflect the unique configuration of the underlying bearer.

Example

Wrap a custom bearer with a name and file cache:

from nebius.sdk import SDK
from nebius.aio.token.token import NamedBearer, Bearer, Receiver, Token
from nebius.aio.token.file_cache.async_renewable_bearer import (
    AsynchronousRenewableFileCacheBearer
)

class SomeCustomHeavyLoadBearer(Bearer):
    def receiver(self) -> Receiver:
        return SomeReceiver()

class SomeReceiver(Receiver):
    async def _fetch(self, timeout=None, options=None) -> Token:
        # Simulate heavy load token fetch
        return Token("heavy-token")

    def can_retry(self, err, options=None) -> bool:
        return False

custom_bearer = SomeCustomHeavyLoadBearer()
named_bearer = NamedBearer(custom_bearer, "heavy-load-bearer")
cached_bearer = AsynchronousRenewableFileCacheBearer(named_bearer)

sdk = SDK(credentials=cached_bearer)
