Enum matrix_sdk_crypto::types::events::UtdCause

pub enum UtdCause {
    Unknown = 0,
    Membership = 1,
}

Our best guess at the reason why an event can’t be decrypted.

Variants

Unknown = 0

We don’t have an explanation for why this UTD happened - it is probably a bug, or a network split between the two homeservers.

Membership = 1

This event was sent when we were not a member of the room (or invited), so it is impossible to decrypt (without MSC3061).

Implementations

impl UtdCause

pub fn determine(raw_event: Option<&Raw<AnySyncTimelineEvent>>) -> Self

Decide the cause of this UTD, based on the evidence we have.

impl PartialEq for UtdCause

fn eq(&self, other: &UtdCause) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
