Struct Variables 

pub struct Variables { /* private fields */ }

Set of variables to parameterize a Tree.

Implementations

impl Variables

pub fn new() -> Self

Creates a new, empty set of variables.

pub fn add(&mut self, name: &str, value: f32) -> Result<Tree>

Adds the variable name to the set.

Errors

Returns Error::VariableAlreadyAdded if the variable already exists in the set.

pub fn set(&mut self, name: &str, value: f32) -> Result<()>

Sets the variable name to value.

Errors

Returns Error::VariableNotFound if the variable does not exist in the set.

Trait Implementations

impl Default for Variables

fn default() -> Self

Returns the “default value” for a type.

impl Drop for Variables

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
