Struct treediff::tools::Recorder

pub struct Recorder<'a, K, V: 'a> {
    pub calls: Vec<ChangeType<'a, K, V>>,
    // some fields omitted
}

A Delegate to record all calls made to it.

It can be useful if you don't want to implement your own custom delegate, but instead just want to quickly see a flat list of all results of the diff run.

Examples

Please see the tests for how to use this type.

Fields

calls: Vec<ChangeType<'a, K, V>>

A list of all calls the diff function made on us.

Trait Implementations

impl<'a, K: Debug, V: Debug + 'a> Debug for Recorder<'a, K, V>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<'a, K: PartialEq, V: PartialEq + 'a> PartialEq for Recorder<'a, K, V>

fn eq(&self, __arg_0: &Recorder<'a, K, V>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Recorder<'a, K, V>) -> bool

This method tests for !=.

impl<'a, K, V> Default for Recorder<'a, K, V>

fn default() -> Self

Returns the "default value" for a type.

impl<'a, K, V> Delegate<'a, K, V> for Recorder<'a, K, V> where K: Clone

fn push<'b>(&mut self, k: &'b K)

... we recurse into the Value at the given Key.

fn pop(&mut self)

... we have processed all items and leave the object previously pushed.

fn removed<'b>(&mut self, k: &'b K, v: &'a V)

... the Value v at the given Key k should be removed.

fn added<'b>(&mut self, k: &'b K, v: &'a V)

.. the Value v at the given Key k should be added.

fn unchanged<'b>(&mut self, v: &'a V)

The Value v was not changed.

fn modified<'b>(&mut self, v1: &'a V, v2: &'a V)

... the old Value was modified, and is now the new Value.
