Struct Attributes 

pub struct Attributes { /* private fields */ }

Attributes can be used to customize the layout of DOT elements, i.e., Nodes, Edges or Graphs. Please note that the attribute names and values are case-sensetive in DOT. A list of supported attributes can be found here: [https://graphviz.org/doc/info/attrs.html]

Implementations

impl Attributes

A wrapper that contains all attributes for a specific element, i.e., Nodes or Edges.

pub fn add<T: Into<String>>(&mut self, key: &'static str, value: T)

Adds a new attribute key-value pair to the Attributes struct.

Parameters

• key - The attribute key, must be a static string reference.
• value - The attribute value, converted into a String.

Behavior

Pushes a new (key, value) tuple onto the inner vector. The value is converted into a String using the Into trait.

pub fn remove(&mut self, key: &'static str)

Removes an entry from the attributes.

Parameters

• key - The attribute key to remove

Behavior

Iterates through inner to find the position of the entry with the matching key. If found, removes the entry at that position using Vec::remove.

Trait Implementations

impl Clone for Attributes

fn clone(&self) -> Attributes

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Attributes

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Attributes

fn default() -> Attributes

Returns the “default value” for a type.

impl Display for Attributes

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Attributes

fn eq(&self, other: &Attributes) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
