Enum GeneratorChanges 

pub enum GeneratorChanges<Index> {
    None,
    LenOnly,
    Range(Range<Index>),
    Any,
}

Indicates whether an update to a DataGenerator has changed

Variants

None

None indicates that no changes to the data has occurred.

LenOnly

Indicates that DataGenerator::len may have changed but generated values have not changed.

Range(Range<Index>)

Indicates that items in the given range may require an update DataGenerator::generate will be called for each index in the intersection of the given range with the visible data range.

Any

Any indicates that changes to the data set may have occurred.

Trait Implementations

impl<Index: Clone> Clone for GeneratorChanges<Index>

fn clone(&self) -> GeneratorChanges<Index>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Index: Debug> Debug for GeneratorChanges<Index>

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

Formats the value using the given formatter.

impl<Index: PartialEq> PartialEq for GeneratorChanges<Index>

fn eq(&self, other: &GeneratorChanges<Index>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
