Enum MessageReplyOption 

#[non_exhaustive]
pub enum MessageReplyOption {
    Unspecified,
    ReplyMessageFallbackToNewThread,
    ReplyMessageOrFail,
    UnknownValue(UnknownValue),
}

Specifies how to reply to a message. More states might be added in the future.

Working with unknown values

This enum is defined as #[non_exhaustive] because Google Cloud may add additional enum variants at any time. Adding new variants is not considered a breaking change. Applications should write their code in anticipation of:

• New values appearing in future releases of the client library, and
• New values received dynamically, without application changes.

Please consult the Working with enums section in the user guide for some guidelines.

Variants (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.

Unspecified

Default. Starts a new thread. Using this option ignores any thread ID or thread_key that’s included.

ReplyMessageFallbackToNewThread

Creates the message as a reply to the thread specified by thread ID or thread_key. If it fails, the message starts a new thread instead.

ReplyMessageOrFail

Creates the message as a reply to the thread specified by thread ID or thread_key. If a new thread_key is used, a new thread is created. If the message creation fails, a NOT_FOUND error is returned instead.

UnknownValue(UnknownValue)

If set, the enum was initialized with an unknown value.

Applications can examine the value using MessageReplyOption::value or MessageReplyOption::name.

Implementations

impl MessageReplyOption

pub fn value(&self) -> Option<i32>

Gets the enum value.

Returns None if the enum contains an unknown value deserialized from the string representation of enums.

pub fn name(&self) -> Option<&str>

Gets the enum value as a string.

Returns None if the enum contains an unknown value deserialized from the integer representation of enums.
