Enum CallbackPattern 

#[non_exhaustive]
pub enum CallbackPattern {
    Data(Regex),
    Game(Regex),
    Both {
        data: Regex,
        game: Regex,
    },
    Predicate(Arc<dyn Fn(&str) -> bool + Send + Sync>),
}

Pattern to match against callback query data or game short name.

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.

Data(Regex)

Match callback_query.data against this compiled regex.

Game(Regex)

Match callback_query.game_short_name against this compiled regex.

Both

Match both: data against the first regex, game against the second.

Fields

data: Regex

Regex to match against callback_query.data.

game: Regex

Regex to match against callback_query.game_short_name.

Predicate(Arc<dyn Fn(&str) -> bool + Send + Sync>)

Match callback_query.data using an arbitrary predicate function.

This covers Python’s callable(data) and isinstance(data, type) patterns in a Rust-idiomatic way. The predicate receives the data string and returns true if the callback query should be handled.

Trait Implementations

impl Clone for CallbackPattern

fn clone(&self) -> CallbackPattern

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
