Struct DotPrinter

pub struct DotPrinter<O: Write> {
    output: O,
    next_id: usize,
    settings: DotPrinterSettings,
}

A visitor of the radix trie that will print the tree in “dot” notation.

See ‘DOT Language | Graphviz’ for information about syntax and example of the language.

Fields

output: O

next_id: usize

settings: DotPrinterSettings

Implementations

impl<O: Write> DotPrinter<O>

pub fn print<K, V, const PREFIX_LEN: usize, A: Allocator>( output: O, tree: &TreeMap<K, V, PREFIX_LEN, A>, settings: DotPrinterSettings, ) -> Option<Result<()>>

where K: Display, V: Display,

Write the dot-format of the given tree to the given output.

pub(crate) unsafe fn print_tree<K, V, const PREFIX_LEN: usize>( output: O, tree: &OpaqueNodePtr<K, V, PREFIX_LEN>, settings: DotPrinterSettings, ) -> Result<()>

where K: Display, V: Display,

Write the dot-format of the given tree to the given output.

Safety

• For the duration of this function, the given node and all its children nodes must not get mutated.
