MaxTokensLimiter

This extension adds a validator to limit the maximum number of tokens in a GraphQL document sent to the server.

Usage example:

import strawberry
from strawberry.extensions import MaxTokensLimiter


@strawberry.type
class Query:
    @strawberry.field
    def hello(self) -> str:
        return "Hello, world!"


schema = strawberry.Schema(
    Query,
    extensions=[
        MaxTokensLimiter(max_token_count=1000),
    ],
)

With the above configuration, if a client sends a query with more than 1000 tokens, the server will respond with an error message.
