fn graph_id(&self) -> Id

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Must return a DOT compatible identifier naming the graph.

fn node_id(&self, n: &&'q DepNode) -> Id

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Maps n to a unique identifier with respect to self. The implementor is responsible for ensuring that the returned name is a valid DOT identifier.

fn node_label(&self, n: &&'q DepNode) -> LabelText

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Maps n to a label that will be used in the rendered output. The label need not be unique, and may be the empty string; the default is just the output from node_id.

fn node_shape(&'a self, _node: &Self::Node) -> Option<LabelText<'a>>

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Maps n to one of the [graphviz shape names][1]. If None is returned, no shape attribute is specified.

fn edge_label(&'a self, _e: &Self::Edge) -> LabelText<'a>

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Maps e to a label that will be used in the rendered output. The label need not be unique, and may be the empty string; the default is in fact the empty string.

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Maps n to a style that will be used in the rendered output.
