Struct FilterMask 

pub struct FilterMask(/* private fields */);

The panel’s per-type filter state.

The value FILTER_ALL means “All” mode — every message is visible and no individual chip is highlighted. Any other value is an explicit selection set: a message is visible iff its message_bit is set.

Toggle semantics (matching the spec scenarios):

• Toggling a chip while in All mode leaves All and narrows to only that type.
• Toggling a chip in selection mode flips its bit; emptying the set returns to All.
• FilterMask::reset returns to All unconditionally.

Implementations

impl FilterMask

pub fn all() -> Self

The default All mask.

pub fn is_all(self) -> bool

Returns true when in All mode (every message visible).

pub fn reset(&mut self)

Resets to All mode.

pub fn toggle(&mut self, bit: u16)

Toggles a single chip bit, applying the All-mode transition rules.

pub fn matches(self, msg: &BrokerMessage) -> bool

Returns true when the given message passes the active filter.

pub fn is_chip_active(self, bit: u16) -> bool

Returns true when a chip is part of the active explicit selection. Always false in All mode (no individual chip is “selected”).

Trait Implementations

impl Clone for FilterMask

fn clone(&self) -> FilterMask

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for FilterMask

impl Debug for FilterMask

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

Formats the value using the given formatter.

impl Default for FilterMask

fn default() -> Self

Returns the “default value” for a type.

impl Eq for FilterMask

impl PartialEq for FilterMask

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

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

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
