Struct arithmetic_parser::Block

pub struct Block<'a, T> where
    T: Grammar,  {
    pub statements: Vec<SpannedStatement<'a, T>>,
    pub return_value: Option<Box<SpannedExpr<'a, T>>>,
}

Block of statements.

A block may end with a return expression, e.g., { x = 1; x }.

Fields

statements: Vec<SpannedStatement<'a, T>>

Statements in the block.

return_value: Option<Box<SpannedExpr<'a, T>>>

The last statement in the block which is returned from the block.

Implementations

impl<T: Grammar, '_> Block<'_, T>

pub fn empty() -> Self

Creates an empty block.

Trait Implementations

impl<T: Grammar, '_> Clone for Block<'_, T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, T: Debug> Debug for Block<'a, T> where
    T: Grammar, 

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

Formats the value using the given formatter.

impl<T, '_> PartialEq<Block<'_, T>> for Block<'_, T> where
    T: Grammar,
