Overview

TokenDetails is a class providing details of the token string and the token’s associated metadata, constructed from the response from Ably when request in a token via the REST API.

Ruby Time objects are supported in place of Ably ms since epoch time fields. However, if a numeric is provided it must always be expressed in milliseconds as the Ably API always uses milliseconds for time fields.

TOKEN_EXPIRY_BUFFER =

Buffer in seconds before a token is considered unusable For example, if buffer is 10s, the token can no longer be used for new requests 9s before it expires
