Struct AxisId 

pub struct AxisId(pub u32);

A unique identifier for an axis.

Supports both standard axes (X/Y primary/secondary) and unlimited custom axes. Custom axes can be created by ID or by name using hash-based ID generation.

Tuple Fields

0: u32

Implementations

impl AxisId

pub const X_PRIMARY: AxisId

Primary X axis (bottom).

pub const Y_PRIMARY: AxisId

Primary Y axis (left).

pub const X_SECONDARY: AxisId

Secondary X axis (top).

pub const Y_SECONDARY: AxisId

Secondary Y axis (right).

pub fn custom(id: u32) -> Self

Create a custom axis ID.

IDs 0-3 are reserved for standard axes.

pub fn from_name(name: &str) -> Self

Create an axis ID from a name using FNV-1a hash.

This allows referencing axes by name in a consistent way. The same name will always produce the same ID.

Example

let pressure_axis = AxisId::from_name("pressure");
// Use the same name to reference the axis later
series.y_axis = AxisId::from_name("pressure");

pub fn is_standard(&self) -> bool

Check if this is a standard (built-in) axis.

pub fn is_custom(&self) -> bool

Check if this is a custom axis.

pub fn raw(&self) -> u32

Get the raw ID value.

Trait Implementations

impl Clone for AxisId

fn clone(&self) -> AxisId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AxisId

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

Formats the value using the given formatter.

impl Default for AxisId

fn default() -> AxisId

Returns the “default value” for a type.

impl Hash for AxisId

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 PartialEq for AxisId

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