Struct V2ipScalingSettings 

pub struct V2ipScalingSettings {
    pub mode: MxrSignalType,
    pub refresh: u16,
    pub flags: u8,
}

A V2IP output’s scaling mode, refresh rate and flags.

Fields

mode: MxrSignalType

The signal type the output scales to.

refresh: u16

Refresh rate in Hz.

flags: u8

The flag bits below.

Implementations

impl V2ipScalingSettings

pub const fn configured_mode(&self) -> Option<(MxrSignalType, u16)>

The mode this sink is configured to scale to, None when it has none.

The two are distinct on the wire: a sink with no mode configured leaves SCALING_FLAG_MODE_VALID clear, and never sets it over a zero mode.

Trust it only where the sender reports crate::DeviceInfo::config_initialised. Firmware without that builds this block over uninitialised stack, where the valid bit itself is noise.

pub const fn auto_scaling(&self) -> Option<bool>

Whether the output scales automatically, None when the sender did not say.

pub const fn match_source(&self) -> Option<bool>

Whether the output follows its source’s format, None when the device has never said.

Firmware with this option announces it on every configuration it sends about itself, so a device that has reported it once is known to have it. The cached block accumulates its validity bits, so a later write carrying only the first options group does not take that back.

Reported only from a sender announcing crate::DeviceInfo::config_initialised, so this needs no caveat of its own: no firmware has these options without that announcement, and one that lacks it would be reporting uninitialised stack. That is the difference from Self::configured_mode, which is reported from any sender because a mode can be genuine on one of those.

pub const fn skip_420(&self) -> Option<bool>

Whether the output declines 4:2:0 rather than scaling it, None when the device has never said. Reported on the same terms as Self::match_source, which shares its validity bit.

pub fn merge(self, previous: Self) -> Self

Folds a received scaling config onto the cached one, field by field.

A write carries the mode or the options alone, so taking the block wholesale would drop whichever half was not being written. The options branch replaces the option bit rather than adding to it, which is what lets an options-only write clear SCALING_FLAG_AUTO_SCALING.
