Struct undo::Builder

pub struct Builder { /* fields omitted */ }

A builder for a record.

Examples

Builder::new()
    .capacity(100)
    .limit(100)
    .saved(false)
    .default()

Methods

impl Builder

pub fn new() -> Builder

Returns a builder for a record.

pub fn capacity(&mut self, capacity: usize) -> &mut Builder

Sets the capacity for the record.

pub fn limit(&mut self, limit: usize) -> &mut Builder

Sets the limit for the record.

Panics

Panics if limit is 0.

pub fn saved(&mut self, saved: bool) -> &mut Builder

Sets if the target is initially in a saved state. By default the target is in a saved state.

pub fn build<T>(&self, target: T) -> Record<T>

Builds the record.

pub fn build_with<T>(
    &self,
    target: T,
    slot: impl FnMut(Signal) + 'static
) -> Record<T>

Builds the record with the slot.

pub fn default<T: Default>(&self) -> Record<T>

Creates the record with a default target.

pub fn default_with<T: Default>(
    &self,
    slot: impl FnMut(Signal) + 'static
) -> Record<T>

Creates the record with a default target and with the slot.

Trait Implementations

impl Clone for Builder

fn clone(&self) -> Builder

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Builder

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

Formats the value using the given formatter.

impl Default for Builder

fn default() -> Self

Returns the "default value" for a type.

impl Eq for Builder

impl Hash for Builder

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl Ord for Builder

fn cmp(&self, other: &Builder) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use] fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use] fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use] fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<Builder> for Builder

fn eq(&self, other: &Builder) -> bool

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

fn ne(&self, other: &Builder) -> bool

This method tests for !=.

impl PartialOrd<Builder> for Builder

fn partial_cmp(&self, other: &Builder) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Builder) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Builder) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Builder) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Builder) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
