Struct Variables 

pub struct Variables { /* private fields */ }

Collection of variables.

Implementations

impl Variables

pub const fn new() -> Self

Create a new empty variable collection.

pub const fn from_vec(variables: Vec<Variable>) -> Self

Create from a vector of variables.

pub fn add(&mut self, variable: Variable) -> Result<()>

Add a variable.

Errors

Returns error if a variable with the same name already exists.

pub fn get(&self, name: &str) -> Option<&Variable>

Get a variable by name.

pub fn get_mut(&mut self, name: &str) -> Option<&mut Variable>

Get a mutable reference to a variable by name.

pub fn get_by_index(&self, index: usize) -> Option<&Variable>

Get a variable by index.

pub fn contains(&self, name: &str) -> bool

Check if a variable exists.

pub fn len(&self) -> usize

Get the number of variables.

pub fn is_empty(&self) -> bool

Check if empty.

pub fn iter(&self) -> impl Iterator<Item = &Variable>

Get an iterator over variables.

pub fn names(&self) -> Vec<&str>

Get names of all variables.

pub fn coordinates(&self) -> impl Iterator<Item = &Variable>

Get coordinate variables.

pub fn data_variables(&self) -> impl Iterator<Item = &Variable>

Get data variables (non-coordinate).

Trait Implementations
