Struct scpi::Context

pub struct Context<'a> {
    pub mav: bool,
    pub user: &'a dyn Any,
}

Context in which to execute a message.

Useful when multiple sources can execute commands.

Fields

mav: bool

Does output buffer contain data?

user: &'a dyn Any

User context data.

Do not use this to pass application data! Use traits instead. It’s only intended to pass along data from whatever context is running a command.

For example: User authentication information if the call comes from an authenticated interface or port number if the call comes from a serial port.

pub fn new() -> Self

pub fn new_with_user(user: &'a dyn Any) -> Self

pub fn user<U: Any>(&'a self) -> Option<&'a U>

Returns true if output buffer contains data
