Expand description

An error code for why the process/request was cancelled by the user.

Custom error codes should use the Java package naming convention.

This type can hold an arbitrary string. To build this with a custom value, convert it from a string with ::from() / .into(). To check for values that are not available as a documented variant here, use its string representation, obtained through .as_str().

Variants (Non-exhaustive)

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

User

The user cancelled the verification.

Timeout

The verification process timed out.

Verification processes can define their own timeout parameters.

UnknownTransaction

The device does not know about the given transaction ID.

UnknownMethod

The device does not know how to handle the requested method.

Should be sent for m.key.verification.start messages and messages defined by individual verification processes.

UnexpectedMessage

The device received an unexpected message.

Typically raised when one of the parties is handling the verification out of order.

KeyMismatch

The key was not verified.

UserMismatch

The expected user did not match the user verified.

InvalidMessage

The message received was invalid.

Accepted

An m.key.verification.request was accepted by a different device.

The device receiving this error can ignore the verification request.

MismatchedCommitment

The device receiving this error can ignore the verification request.

MismatchedSas

The SAS did not match.
