Struct ladspa::ControlHint
[−]
[src]
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
Returns an empty set of flags.
fn all() -> ControlHint
Returns the set containing all flags.
fn bits(&self) -> i32
Returns the raw value of the flags currently stored.
fn from_bits(bits: i32) -> Option<ControlHint>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
fn from_bits_truncate(bits: i32) -> ControlHint
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
fn is_empty(&self) -> bool
Returns true if no flags are currently stored.
fn is_all(&self) -> bool
Returns true if all flags are currently set.
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)
Inserts the specified flags in-place.
fn remove(&mut self, other: ControlHint)
Removes the specified flags in-place.
fn toggle(&mut self, other: ControlHint)
Toggles the specified flags in-place.
