Available on crate features e2e-encryption and qrcode only.

Expand description

Error type describing errors that happen while QR data is being decoded.

Variants

`Header`

The QR code data is missing the mandatory Matrix header.

`Utf8(FromUtf8Error)`

The QR code data is containing an invalid, non UTF-8, flow id.

`Mode(u8)`

The QR code data is using an unsupported or invalid verification mode.

`Read(Error)`

The QR code data does not contain all the necessary fields.

`SharedSecret(usize)`

The QR code data uses an invalid shared secret.

`Version(u8)`

The QR code data uses an invalid or unsupported version.

`Keys(KeyError)`

The QR code data doesn’t contain valid ed25519 keys.
