Struct Aes 

pub struct Aes {
    pub mappings: Vec<AesMapping>,
    pub after_scale: Vec<AfterScaleSpec>,
}

Builder for aesthetic mappings.

Fields

mappings: Vec<AesMapping>

after_scale: Vec<AfterScaleSpec>

Post-scale color derivations (after_scale).

Implementations

impl Aes

pub fn new() -> Self

pub fn after_scale_fill_from_color(self, lightness: f64) -> Self

Set fill to the mapped color with adjusted lightness (R’s aes(fill = after_scale(...))). lightness in -1.0..=1.0: positive lightens toward white, negative darkens toward black.

pub fn after_scale_color_from_fill(self, lightness: f64) -> Self

Set color to the mapped fill with adjusted lightness — useful for a darker border around a filled shape (color = after_scale(darken(fill))).

pub fn stage(self, aesthetic: Aesthetic, start: &str, after_stat: &str) -> Self

stage(start, after_stat): map aesthetic from start before the stat and re-map it from after_stat afterwards (R’s stage()).

pub fn x(self, col: &str) -> Self

pub fn y(self, col: &str) -> Self

pub fn color(self, col: &str) -> Self

pub fn fill(self, col: &str) -> Self

pub fn size(self, col: &str) -> Self

pub fn shape(self, col: &str) -> Self

pub fn alpha(self, col: &str) -> Self

pub fn group(self, col: &str) -> Self

pub fn ymin(self, col: &str) -> Self

pub fn ymax(self, col: &str) -> Self

pub fn label(self, col: &str) -> Self

pub fn weight(self, col: &str) -> Self

pub fn xend(self, col: &str) -> Self

pub fn yend(self, col: &str) -> Self

pub fn xmin(self, col: &str) -> Self

pub fn xmax(self, col: &str) -> Self

pub fn angle(self, col: &str) -> Self

pub fn radius(self, col: &str) -> Self

pub fn linetype(self, col: &str) -> Self

pub fn after_stat_y(self, col: &str) -> Self

Map a stat-computed column to the y aesthetic (e.g., after_stat_y("density")).

pub fn after_stat_x(self, col: &str) -> Self

Map a stat-computed column to the x aesthetic.

pub fn after_stat_fill(self, col: &str) -> Self

Map a stat-computed column to the fill aesthetic.

pub fn after_stat_color(self, col: &str) -> Self

Map a stat-computed column to the color aesthetic.

pub fn after_stat_size(self, col: &str) -> Self

Map a stat-computed column to the size aesthetic.

pub fn after_stat_alpha(self, col: &str) -> Self

Map a stat-computed column to the alpha aesthetic.

pub fn get_mapping(&self, aes: &Aesthetic) -> Option<&str>

Get the column mapped to a specific aesthetic.

pub fn merge(&self, other: &Aes) -> Aes

Merge another Aes into this one. The other’s mappings override on conflict.

Trait Implementations

impl Clone for Aes

fn clone(&self) -> Aes

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Aes

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

Formats the value using the given formatter.

impl Default for Aes

fn default() -> Aes

Returns the “default value” for a type.
