Struct GraphStream 

pub struct GraphStream { /* private fields */ }

An iterator-backed stream of graph edges (u, v).

Use GraphStream::from_edges to create a stream from a vector, or GraphStream::from_fn to wrap a lazy generator (e.g. reading a file line-by-line without loading it all).

Implementations

impl GraphStream

pub fn from_edges(edges: Vec<(usize, usize)>) -> Self

Create a GraphStream from an owned vector of edges.

pub fn from_fn(f: impl FnMut() -> Option<(usize, usize)> + 'static) -> Self

Create a GraphStream from a closure that produces Some((u,v)) or None.

pub fn next_edge(&mut self) -> Option<(usize, usize)>

Advance the stream by one edge. Returns None when exhausted.
