Struct GraphBuilder

pub struct GraphBuilder {
    pub label_names_order: LabelNamesOrder,
    /* private fields */
}

Dynamically builds a small graph in memory

Examples

Directories and contents

use swh_graph::swhid;
use swh_graph::graph_builder::GraphBuilder;
use swh_graph::labels::Permission;

let mut builder = GraphBuilder::default();
let a = builder
    .node(swhid!(swh:1:dir:0000000000000000000000000000000000000010)).unwrap()
    .done();
let b = builder
    .node(swhid!(swh:1:dir:0000000000000000000000000000000000000020)).unwrap()
    .done();
let c = builder
    .node(swhid!(swh:1:cnt:0000000000000000000000000000000000000030)).unwrap()
    .done();
builder.dir_arc(a, b, Permission::Directory, b"tests");

Implementations

impl GraphBuilder

pub fn node(&mut self, swhid: SWHID) -> Result<NodeBuilder<'_>>

Adds a node to the graph.

Returns Err if there is already a node with this SWHID.

pub fn arc(&mut self, src: NodeId, dst: NodeId)

Adds an unlabeled arc to the graph

pub fn dir_arc<P: Into<Permission>, N: Into<Vec<u8>>>( &mut self, src: NodeId, dst: NodeId, permission: P, name: N, )

Adds a labeled dir->{cnt,dir,rev} arc to the graph

pub fn snp_arc<N: Into<Vec<u8>>>(&mut self, src: NodeId, dst: NodeId, name: N)

Adds a labeled snp->{cnt,dir,rev,rel} arc to the graph

pub fn ori_arc( &mut self, src: NodeId, dst: NodeId, status: VisitStatus, timestamp: u64, )

Adds a labeled ori->snp arc to the graph

pub fn l_arc<L: Into<EdgeLabel>>(&mut self, src: NodeId, dst: NodeId, label: L)

Adds a labeled arc to the graph

pub fn done(&self) -> Result<BuiltGraph>

Trait Implementations
