Struct leo_ast::common::array_dimensions::ArrayDimensions

pub struct ArrayDimensions(pub Vec<PositiveNumber>);

A vector of positive numbers that represent array dimensions. Can be used in an array [Type] or an array initializer [Expression].

Implementations

impl ArrayDimensions

pub fn push_usize(&mut self, number: usize, span: Span)

Creates a new PositiveNumber from the given usize and Span. Appends the new PositiveNumber to the array dimensions.

pub fn append(&mut self, other: &mut ArrayDimensions)

Appends a vector of array dimensions to the self array dimensions.

pub fn to_strings(&self) -> Vec<String>

Returns the array dimensions as strings.

pub fn is_empty(&self) -> bool

Returns true if the all array dimensions have been removed.

This method is called after repeated calls to remove_first.

pub fn is_zero(&self) -> bool

Returns true if there is an array dimension equal to zero.

pub fn first(&self) -> Option<&PositiveNumber>

Returns the first dimension of the array.

pub fn remove_first(&mut self) -> Option<PositiveNumber>

Attempts to remove the first dimension from the array.

If the first dimension exists, then remove and return Some(PositiveNumber). If the first dimension does not exist, then return None.

pub fn remove_last(&mut self) -> Option<PositiveNumber>

Attempts to remove the last dimension from the array.

If the last dimension exists, then remove and return Some(PositiveNumber). If the last dimension does not exist, then return None.
