Enum AllocationStrategy 

pub enum AllocationStrategy {
    BestFit,
    PowerOfTwo,
    Static,
}

Describes generically an AllocationStrategy, meaning how the memory is increased when the available memory is insufficient.

Variants

BestFit

Increases the memory so that it perfectly fits the new size requirements. This may lead to a lot of reallocations but has the benefit that no byte is wasted.

PowerOfTwo

Increases the memory by rounding the increased memory size up to the next power of two. Reduces reallocations a lot at the cost of increased memory usage.

Static

The memory is not increased. This may lead to an out-of-memory error when allocating.

Trait Implementations

impl Clone for AllocationStrategy

fn clone(&self) -> AllocationStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AllocationStrategy

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

Formats the value using the given formatter.

impl Default for AllocationStrategy

fn default() -> AllocationStrategy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AllocationStrategy

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AllocationStrategy

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

impl Serialize for AllocationStrategy

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for AllocationStrategy
