Methods

impl Reaction

fn channel(&self) -> Result<Channel>

Retrieves the associated the reaction was made in.

If the cache is enabled, this will search for the already-cached channel. If not - or the channel was not found - this will perform a request over the REST API for the channel.

Requires the Read Message History permission.

fn delete(&self) -> Result<()>

Deletes the reaction, but only if the current user is the user who made the reaction or has permission to.

Requires the Manage Messages permission, if the current user did not perform the reaction.

Errors

If the cache is enabled, then returns a ModelError::InvalidPermissions if the current user does not have the required permissions.

fn message(&self) -> Result<Message>

Retrieves the Message associated with this reaction.

Requires the Read Message History permission.

Note: This will send a request to the REST API. Prefer maintaining your own message cache or otherwise having the message available if possible.

fn user(&self) -> Result<User>

Retrieves the user that made the reaction.

If the cache is enabled, this will search for the already-cached user. If not - or the user was not found - this will perform a request over the REST API for the user.

fn users<R, U>(
    &self,
    reaction_type: R,
    limit: Option<u8>,
    after: Option<U>
) -> Result<Vec<User>> where
    R: Into<ReactionType>,
    U: Into<UserId>, 

Retrieves the list of Users who have reacted to a Message with a certain Emoji.

The default limit is 50 - specify otherwise to receive a different maximum number of users. The maximum that may be retrieve at a time is 100, if a greater number is provided then it is automatically reduced.

The optional after attribute is to retrieve the users after a certain user. This is useful for pagination.

Requires the Read Message History permission.

Note: This will send a request to the REST API.

Errors

Returns a ModelError::InvalidPermissions if the current user does not have the required permissions.
