pub struct UndoManager(/* private fields */);Expand description
UndoManager can be used to undo and redo the changes made to the document with a certain peer.
Implementations§
Source§impl UndoManager
impl UndoManager
Sourcepub fn undo(&mut self) -> LoroResult<bool>
pub fn undo(&mut self) -> LoroResult<bool>
Undo the last change made by the peer.
Sourcepub fn redo(&mut self) -> LoroResult<bool>
pub fn redo(&mut self) -> LoroResult<bool>
Redo the last change made by the peer.
Sourcepub fn record_new_checkpoint(&mut self) -> LoroResult<()>
pub fn record_new_checkpoint(&mut self) -> LoroResult<()>
Record a new checkpoint.
Sourcepub fn add_exclude_origin_prefix(&mut self, prefix: &str)
pub fn add_exclude_origin_prefix(&mut self, prefix: &str)
If a local event’s origin matches the given prefix, it will not be recorded in the undo stack.
Sourcepub fn set_max_undo_steps(&mut self, size: usize)
pub fn set_max_undo_steps(&mut self, size: usize)
Set the maximum number of undo steps. The default value is 100.
Sourcepub fn set_merge_interval(&mut self, interval: i64)
pub fn set_merge_interval(&mut self, interval: i64)
Set the merge interval in ms. The default value is 0, which means no merge.
Sourcepub fn set_on_push(&mut self, on_push: Option<OnPush>)
pub fn set_on_push(&mut self, on_push: Option<OnPush>)
Set the listener for push events. The listener will be called when a new undo/redo item is pushed into the stack.
Sourcepub fn set_on_pop(&mut self, on_pop: Option<OnPop>)
pub fn set_on_pop(&mut self, on_pop: Option<OnPop>)
Set the listener for pop events. The listener will be called when an undo/redo item is popped from the stack.

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().

painted.white();Source§fn bright_black(&self) -> Painted<&T>

Source§fn bg(&self, value: Color) -> Painted<&T>
fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().

Source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();Source§fn rapid_blink(&self) -> Painted<&T>
fn rapid_blink(&self) -> Painted<&T>
Source§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>
resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
