Implementations

impl MlsGroupConfigBuilder

pub fn new() -> Self

Creates a new builder with default values.

pub fn wire_format_policy(self, wire_format_policy: WireFormatPolicy) -> Self

Sets the wire_format property of the MlsGroupConfig.

pub fn padding_size(self, padding_size: usize) -> Self

Sets the padding_size property of the MlsGroupConfig.

pub fn max_past_epochs(self, max_past_epochs: usize) -> Self

Sets the max_past_epochs property of the MlsGroupConfig. This allows application messages from previous epochs to be decrypted.

WARNING

This feature enables the storage of message secrets from past epochs. It is a trade-off between functionality and forward secrecy and should only be enabled if the Delivery Service cannot guarantee that application messages will be sent in the same epoch in which they were generated. The number for max_epochs should be as low as possible.
