Enum DiffOptimizationHint

pub enum DiffOptimizationHint {
    Default,
    SizeSource,
    SizeTarget,
    SizeValue(usize),
    SizePercentage(f64),
}

Optimization hint used in calculating change between two intermediate data.

Variants

Default

Don’t assume any optimization.

SizeSource

Put entire new object if change information size is greater than source (old) size.

SizeTarget

Put entire new object if change information size is greater than target (new) size.

SizeValue(usize)

Put entire new object if change information size is greater than bytesize threshold.

Tuple Fields

0: usize

Bytesize threshold.

SizePercentage(f64)

Put entire new object if change information size is greater than percentage of source size.

Tuple Fields

0: f64

Percentage threshold.

Trait Implementations

impl Clone for DiffOptimizationHint

fn clone(&self) -> DiffOptimizationHint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DiffOptimizationHint

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

Formats the value using the given formatter.

impl Default for DiffOptimizationHint

fn default() -> DiffOptimizationHint

Returns the “default value” for a type.

impl PartialEq for DiffOptimizationHint

fn eq(&self, other: &DiffOptimizationHint) -> 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.
