Source§impl UndoManager
impl UndoManager
Sourcepub fn undo(&self) -> LoroResult<bool>
pub fn undo(&self) -> LoroResult<bool>
Undo the last change made by the peer.
Sourcepub fn redo(&self) -> LoroResult<bool>
pub fn redo(&self) -> LoroResult<bool>
Redo the last change made by the peer.
Sourcepub fn record_new_checkpoint(&self) -> LoroResult<()>
pub fn record_new_checkpoint(&self) -> LoroResult<()>

Sourcepub fn undo_count(&self) -> u32
pub fn undo_count(&self) -> u32
How many times the undo manager can undo.
Sourcepub fn redo_count(&self) -> u32
pub fn redo_count(&self) -> u32
How many times the undo manager can redo.
Sourcepub fn add_exclude_origin_prefix(&self, prefix: &str)
pub fn add_exclude_origin_prefix(&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(&self, size: u32)
pub fn set_max_undo_steps(&self, size: u32)
Set the maximum number of undo steps. The default value is 100.
Sourcepub fn set_merge_interval(&self, interval: i64)
pub fn set_merge_interval(&self, interval: i64)
Set the merge interval in ms. The default value is 0, which means no merge.
Sourcepub fn set_on_push(&self, on_push: Option<Arc<dyn OnPush>>)
pub fn set_on_push(&self, on_push: Option<Arc<dyn 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(&self, on_pop: Option<Arc<dyn OnPop>>)
pub fn set_on_pop(&self, on_pop: Option<Arc<dyn OnPop>>)
Set the listener for pop events. The listener will be called when an undo/redo item is popped from the stack.
pub fn group_start(&self) -> LoroResult<()>
pub fn group_end(&self)
pub fn peer(&self) -> PeerID
pub fn top_undo_meta(&self) -> Option<UndoItemMeta>
pub fn top_redo_meta(&self) -> Option<UndoItemMeta>

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().
use yansi::Paint;
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().
use yansi::Paint;
painted.on_red();Source§fn on_primary(&self) -> Painted<&T>

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);
