Implementations

impl<L> GenericPerspectiveFunction<L>

pub fn infinity_or(&self, f: impl FnOnce(&L) -> f32) -> f32

Returns f32::INFINITY or the result of a function on the length value.

Trait Implementations

impl<L: Clone> Clone for GenericPerspectiveFunction<L>

fn clone(&self) -> GenericPerspectiveFunction<L>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<L: Debug> Debug for GenericPerspectiveFunction<L>

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

Formats the value using the given formatter.

impl<'de, L> Deserialize<'de> for GenericPerspectiveFunction<L>

where L: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<L> MallocSizeOf for GenericPerspectiveFunction<L>

where L: MallocSizeOf,

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl<L: PartialEq> PartialEq for GenericPerspectiveFunction<L>

fn eq(&self, other: &GenericPerspectiveFunction<L>) -> 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.

where __S: Serializer,

Serialize this value into the given Serde serializer.

where L: SpecifiedValueInfo,

const SUPPORTED_TYPES: u8 = _

Supported CssTypes by the given value type.

fn collect_completion_keywords(_f: &mut dyn FnMut(&[&'static str]))

Collect value starting words for the given specified value type. This includes keyword and function names which can appear at the beginning of a value of this type.
