Enum rerun::sdk::components::Colormap

pub enum Colormap {
    Grayscale = 1,

Component: Colormap for mapping scalar values within a given range to a color.

This provides a number of popular pre-defined colormaps. In the future, the Rerun Viewer will allow users to define their own colormaps, but currently the Viewer is limited to the types defined here.

Variants

Grayscale = 1

A simple black to white gradient.

This is a sRGB gray gradient which is perceptually uniform.

Inferno = 2

The Inferno colormap from Matplotlib.

This is a perceptually uniform colormap. It interpolates from black to red to bright yellow.

Magma = 3

The Magma colormap from Matplotlib.

This is a perceptually uniform colormap. It interpolates from black to purple to white.

Plasma = 4

The Plasma colormap from Matplotlib.

This is a perceptually uniform colormap. It interpolates from dark blue to purple to yellow.

Turbo = 5

Google’s Turbo colormap map.

This is a perceptually non-uniform rainbow colormap addressing many issues of more traditional rainbow colormaps like Jet. It is more perceptually uniform without sharp transitions and is more colorblind-friendly. Details: https://research.google/blog/turbo-an-improved-rainbow-colormap-for-visualization/

Viridis = 6

The Viridis colormap from Matplotlib

This is a perceptually uniform colormap which is robust to color blindness. It interpolates from dark purple to green to yellow.

CyanToYellow = 7

Rasmusgo’s Cyan to Yellow colormap

This is a perceptually uniform colormap which is robust to color blindness. It is especially suited for visualizing signed values. It interpolates from cyan to blue to dark gray to brass to yellow.

Implementations

impl Colormap

pub fn from_u8(value: u8) -> Option<Colormap>

Instantiate a new Colormap from a u8 value.

Returns None if the value doesn’t match any of the enum’s arms.

Trait Implementations

impl Clone for Colormap

fn clone(&self) -> Colormap

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Component for Colormap

fn descriptor() -> ComponentDescriptor

Returns the complete ComponentDescriptor for this Component.

fn name() -> ComponentName

The fully-qualified name of this component, e.g. rerun.components.Position2D.

impl Debug for Colormap

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

Formats the value using the given formatter.

impl Default for Colormap

fn default() -> Colormap

Returns the “default value” for a type.

impl Display for Colormap

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

Formats the value using the given formatter.

impl Enum for Colormap

fn variants() -> &'static [Colormap]

All variants, in the order they appear in the enum.

fn docstring_md(self) -> &'static str

Markdown docstring for the given enum variant.

impl Hash for Colormap

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

where __H: Hasher,

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 Loggable for Colormap

fn arrow_datatype() -> DataType

The underlying arrow::datatypes::DataType, excluding datatype extensions.

fn to_arrow_opt<'a>( data: impl IntoIterator<Item = Option<impl Into<Cow<'a, Colormap>>>>, ) -> Result<Arc<dyn Array>, SerializationError>

where Colormap: Clone + 'a,

Given an iterator of options of owned or reference values to the current Loggable, serializes them into an Arrow array.

fn from_arrow_opt( arrow_data: &dyn Array, ) -> Result<Vec<Option<Colormap>>, DeserializationError>

where Colormap: Sized,

Given an Arrow array, deserializes it into a collection of optional Loggables.

fn arrow_empty() -> Arc<dyn Array>

fn to_arrow<'a>( data: impl IntoIterator<Item = impl Into<Cow<'a, Self>>>, ) -> Result<Arc<dyn Array>, SerializationError>

where Self: 'a,

Given an iterator of owned or reference values to the current Loggable, serializes them into an Arrow array.

fn from_arrow(data: &dyn Array) -> Result<Vec<Self>, DeserializationError>

Given an Arrow array, deserializes it into a collection of Loggables.

impl PartialEq for Colormap

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

impl SizeBytes for Colormap

fn heap_size_bytes(&self) -> u64

Returns how many bytes self uses on the heap.

fn is_pod() -> bool

Is Self just plain old data?

fn total_size_bytes(&self) -> u64

Returns the total size of self in bytes, accounting for both stack and heap space.

fn stack_size_bytes(&self) -> u64

Returns the total size of self on the stack, in bytes.

impl TypedComponentFallbackProvider<Colormap> for TensorView

fn fallback_for(&self, _ctx: &QueryContext<'_>) -> Colormap

impl Copy for Colormap

impl Eq for Colormap

impl StructuralPartialEq for Colormap
