Struct IterTree

pub struct IterTree {
    pub variants: Vec<IterNode>,
    pub id: u8,
    pub span: Span,
}

Represents complicated iterator structures.

Fields

variants: Vec<IterNode>

The variants of the top-level iterator.

id: u8

The id of the top-level iterator.

span: Span

The span of the top-level iterator.

Implementations

impl IterTree

pub fn get_iter_lengths( &self, lengths: &mut HashMap<u8, (usize, Span, Option<Span>)>, full_span: Span, ) -> Result<(), Error>

Collect lengths of each iterator mapped to the iterators’ ids.

Errors

Returns an error when there is an inconsistency in among iterators (same id, different lengths) or when an iterator with id x contains an iterator with id x.
