/// The Session Mode of the SDK.

/// Depending on the use-case, the SDK can be set to two different session modes:
///
/// * **Application Mode Sessions**:
///   This mode should be used for user-attended programs, which typically have
///   a single long running session that span the applications' lifetime.
///
/// * **Request Mode Sessions**:
///   This mode is intended for servers that use one session per incoming
///   request, and thus have a lot of very short lived sessions.
///
/// Setting the SDK to *request-mode* sessions means that session durations will
/// not be tracked, and sessions will be pre-aggregated before being sent upstream.
/// This applies both to automatic and manually triggered sessions.
///
/// **NOTE**: Support for *request-mode* sessions was added in Sentry `21.2`.
///
/// See the
/// [Documentation on Session Modes](https://develop.sentry.dev/sdk/sessions/#sdk-considerations)
/// for more information.
