Diff is the diff between two versions of a container. It’s used to describe the change of a container and the events.

Internal

Text index variants:

• When wasm is enabled, it should use utf16 indexes.
• When wasm is disabled, it should use unicode indexes.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

List(Delta<Vec<ValueOrHandler>>)

Text(Delta<StringSlice, StyleMeta>)

• When feature wasm is enabled, it should use utf16 indexes.
• When feature wasm is disabled, it should use unicode indexes.

Map(ResolvedMapDelta)

Tree(TreeDiff)

Implementations

impl Diff

pub fn as_list_mut(&mut self) -> Option<&mut Delta<Vec<ValueOrHandler>>>

Optionally returns mutable references to the inner fields if this is a Diff::List, otherwise None

pub fn as_list(&self) -> Option<&Delta<Vec<ValueOrHandler>>>

Optionally returns references to the inner fields if this is a Diff::List, otherwise None

pub fn into_list(self) -> Result<Delta<Vec<ValueOrHandler>>, Self>

Returns the inner fields if this is a Diff::List, otherwise returns back the enum in the Err case of the result

pub fn as_text_mut(&mut self) -> Option<&mut Delta<StringSlice, StyleMeta>>

Optionally returns mutable references to the inner fields if this is a Diff::Text, otherwise None

pub fn as_text(&self) -> Option<&Delta<StringSlice, StyleMeta>>

Optionally returns references to the inner fields if this is a Diff::Text, otherwise None

pub fn into_text(self) -> Result<Delta<StringSlice, StyleMeta>, Self>

Returns the inner fields if this is a Diff::Text, otherwise returns back the enum in the Err case of the result

pub fn as_map_mut(&mut self) -> Option<&mut ResolvedMapDelta>

Optionally returns mutable references to the inner fields if this is a Diff::Map, otherwise None

pub fn as_map(&self) -> Option<&ResolvedMapDelta>

Optionally returns references to the inner fields if this is a Diff::Map, otherwise None

pub fn into_map(self) -> Result<ResolvedMapDelta, Self>

Returns the inner fields if this is a Diff::Map, otherwise returns back the enum in the Err case of the result

pub fn as_tree_mut(&mut self) -> Option<&mut TreeDiff>

Optionally returns mutable references to the inner fields if this is a Diff::Tree, otherwise None

pub fn as_tree(&self) -> Option<&TreeDiff>

Optionally returns references to the inner fields if this is a Diff::Tree, otherwise None

pub fn into_tree(self) -> Result<TreeDiff, Self>

Returns the inner fields if this is a Diff::Tree, otherwise returns back the enum in the Err case of the result
