fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Subscribe

fn default() -> Subscribe

Returns the “default value” for a type.

impl From<Subscribe> for Packet

fn from(control: Subscribe) -> Self

Converts to this type from the input type.

impl PartialEq for Subscribe

fn eq(&self, other: &Subscribe) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool
