Struct DotWrite

pub struct DotWrite<'a, 'b> { /* private fields */ }

A write target for Dot graphs. Use with the write! macro.

Implementations

impl<'a, 'b> DotWrite<'a, 'b>

pub fn set_escape_backslashes(&mut self, escape_backslashes: bool)

Sets a config option for whether backslashes should be escaped. Defaults to true.

This can be set to false if the visitor knows to output graphviz control characters.

pub fn write_fmt(&mut self, args: Arguments<'_>) -> Result

Glue for usage of the write! macro.

This method should generally not be invoked manually, but rather through write! or similar macros (println!, format! etc).

Defining this inherent method allows write! to work without callers needing to import the std::fmt::Write trait.

Trait Implementations

impl<'a, 'b> Write for DotWrite<'a, 'b>

fn write_str(&mut self, s: &str) -> Result

Writes a string slice into this writer, returning whether the write succeeded.

fn write_char(&mut self, c: char) -> Result

Writes a char into this writer, returning whether the write succeeded.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Glue for usage of the write! macro with implementors of this trait.
