Enum SetReservedSpace

pub enum SetReservedSpace {
    Keep,
    ShrinkTo(usize),
    GrowTo(usize),
    Exact(usize),
}

Defines what happens to the reserved space of one of the deque ends on a call to set_reserved_space.

Variants

Keep

The reserved space is not changed.

ShrinkTo(usize)

The reserved space is shrunk to the specified size.

If the current space is less than the wanted size, then this is a no-op.

GrowTo(usize)

The reserved space is grown to the specified size.

If the current space is greater than the wanted size, then this is a no-op.

Exact(usize)

The reserved space is unconditionally changed to the specified size.

Trait Implementations

impl Clone for SetReservedSpace

fn clone(&self) -> SetReservedSpace

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SetReservedSpace

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

Formats the value using the given formatter.

impl PartialEq for SetReservedSpace

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

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

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

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