Binary Tree Error (btree_error)

![CodeBuild] ![Version badge] ![Docs badge]

To reduce repeated implementations of a simple error enum, this crate has been separated from the bforest crates.

Example

```rust use btreeerror::Error; use btreegraph::BTreeGraph;

fn main() { let mut graph: BTreeGraph = BTreeGraph::new(); // Add nodes. graph.addvertex(String::from("Tarzan")); graph.addvertex(String::from("Jane")); // Add a relationship. let err: Error = graph.addedge(String::from("Tarzan"), String::from("Sabor"), String::from("Hates")).unwraperr();

// Assert error was returned.
assert_eq!(err, Error::VertexDoesNotExist);

} ```

Usage

It is doubtful anyone will use this crate by itself, but for completeness, add the following to your Cargo.toml file: toml [dependencies] btree_error = "0.1.0"

Implementation

Please see the API for a the full definition.
