Enum VSRequestPattern

#[repr(C)]
pub enum VSRequestPattern {
    General = 0,
    NoFrameReuse = 1,
    StrictSpatial = 2,
}

Describes the upstream frame request pattern of a filter.

Variants

General = 0

Anything goes. Note that filters that may be requesting beyond the end of a VSNode length in frames (repeating the last frame) should use VSRequestPattern::General) and not any of the other modes.

NoFrameReuse = 1

Will only request an input frame at most once if all output frames are requested exactly one time. This includes filters such as Trim, Reverse, SelectEvery.

StrictSpatial = 2

Only requests frame N to output frame N. The main difference to VSRequestPattern::NoFrameReuse is that the requested frame is always fixed and known ahead of time. Filter examples Lut, Expr (conditionally, see VSRequestPattern::General note) and similar.

Trait Implementations

impl Clone for VSRequestPattern

fn clone(&self) -> VSRequestPattern

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VSRequestPattern

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

Formats the value using the given formatter.

impl Hash for VSRequestPattern

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for VSRequestPattern

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for VSRequestPattern

fn eq(&self, other: &VSRequestPattern) -> 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.

impl PartialOrd for VSRequestPattern

fn partial_cmp(&self, other: &VSRequestPattern) -> Option<Ordering>

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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