Struct CellStream 

pub struct CellStream { /* private fields */ }

A sequence of independently parseable Macaulay2 token streams.

Cell boundaries are expressed by the collection itself. The boundary after its final element is also the end-of-file boundary, so neither fact needs a virtual token in the contained streams.

Implementations

impl CellStream

pub fn new(tokens: TokenStream) -> Result<Self, CellStreamError>

Partitions a complete raw token stream and inserts inferred adjacency.

Errors

Returns CellStreamError when the final tokens require more input before they can form an independently parseable cell.

pub fn from_cells(cells: impl IntoIterator<Item = TokenStream>) -> Self

Creates a stream from token streams already known to be complete cells.

pub fn cells(&self) -> &[TokenStream]

Borrows the independently parseable cells.

pub fn iter( &self, ) -> impl DoubleEndedIterator<Item = &TokenStream> + ExactSizeIterator

Iterates over the independently parseable cells.

pub fn len(&self) -> usize

Returns the number of cells.

pub fn is_empty(&self) -> bool

Reports whether the stream contains no cells.

pub fn into_token_stream(self) -> TokenStream

Flattens the cells back into one token stream.

pub fn to_token_stream(&self) -> TokenStream

Flattens borrowed cells back into one token stream.
