struct.CommandItem

pub struct CommandItem<'a, P: Params> {
    pub name: &'static str,
    pub key: &'static str,
    pub message: &'a InvokeMessage<P>,
}

Represents a custom command.

Fields#

name: &'static str

The name of the command, e.g. handler on #[command] fn handler(value: u64)

key: &'static str

The key of the command item, e.g. value on #[command] fn handler(value: u64)

message: &'a InvokeMessage<P>

The InvokeMessage that was passed to this command.

Trait Implementations#

impl<'de, P: Params> Deserializer<'de> for CommandItem<'de, P>#

A Deserializer wrapper around CommandItem.

If the key doesn’t exist, an error will be returned if the deserialized type is not expecting an optional item. If the key does exist, the value will be called with Value’s Deserializer implementation.

type Error = Error#

The error type that can be returned if some error occurs during deserialization. Read more
