Struct ladspa::ControlHint

pub struct ControlHint {
    // some fields omitted
}

Represents the special properties a control port may hold. These are merely hints as to the use of the port and may be completely ignored by the host. For audio ports, use CONTROL_HINT_NONE. To attach multiple properties, bitwise-or them together. See documentation for the constants beginning with HINT_ for the more information.

Methods

impl ControlHint

fn empty() -> ControlHint

fn intersects(&self, other: ControlHint) -> bool

Returns true if there are flags common to both self and other.

fn contains(&self, other: ControlHint) -> bool

Returns true all of the flags in other are contained within self.

fn insert(&mut self, other: ControlHint)
