Enum InplaceMode 

pub enum InplaceMode {
    Disallow,
    Allow,
}

Permission to attempt in-place structural mutation along an owned path.

Allow still requires unique ownership; it does not grant permission to modify a borrowed value. Use an owned value or an engine-issued InplaceValue with the mode-aware mutation helpers.

Variants

Disallow

Use ordinary mutation, including for uniquely owned values.

Allow

Permit reuse when ownership and alias checks allow it.

Trait Implementations

impl Clone for InplaceMode

fn clone(&self) -> InplaceMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for InplaceMode

impl Debug for InplaceMode

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

Formats the value using the given formatter.

impl Default for InplaceMode

fn default() -> InplaceMode

Returns the “default value” for a type.

impl Eq for InplaceMode

impl PartialEq for InplaceMode

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