    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for UlaVideoFrame

fn cmp(&self, other: &UlaVideoFrame) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<UlaVideoFrame> for UlaVideoFrame

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

This method tests for self and other values to be equal, and is used by ==.

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

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

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for UlaVideoFrame

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where
    __S: Serializer,

Serialize this value into the given Serde serializer.

Returns a horizontal T-state counter after adding an additional T-states required for emulating a memory contention, while rendering lines that require reading video memory.

fn floating_bus_offset(hc: Ts) -> Option<u16>

Returns an optional floating bus horizontal offset for the given horizontal timestamp.

fn snow_interference_coords(_: VideoTs) -> Option<CellCoords>
