Struct RedoubtOption 

pub struct RedoubtOption<T>
where
    T: FastZeroizable + ZeroizeMetadata + ZeroizationProbe,
{ /* private fields */ }

An optional value wrapper with automatic zeroization.

Implementations

impl<T> RedoubtOption<T>

where T: FastZeroizable + ZeroizeMetadata + ZeroizationProbe,

pub fn as_ref(&self) -> Result<&T, RedoubtOptionError>

Returns a reference to the inner value, or an error if None.

pub fn as_mut(&mut self) -> Result<&mut T, RedoubtOptionError>

Returns a mutable reference to the inner value, or an error if None.

pub fn replace(&mut self, value: &mut T)

where T: Default,

Replaces the inner value with a new one, zeroizing both the old value and the source.

pub fn take(&mut self) -> Result<T, RedoubtOptionError>

Takes the value out of the option, leaving None in its place.

pub fn is_some(&self) -> bool

Returns true if the option contains a value.

pub fn is_none(&self) -> bool

Returns true if the option is None.

pub fn as_option(&self) -> &Option<T>

Returns a reference to the inner Option<T>.

pub fn as_mut_option(&mut self) -> &mut Option<T>

Returns a mutable reference to the inner Option<T>.

Trait Implementations

impl<T> AssertZeroizeOnDrop for RedoubtOption<T>

where T: FastZeroizable + ZeroizeMetadata + ZeroizationProbe,

fn clone_sentinel(&self) -> ZeroizeOnDropSentinel

Clones the internal ZeroizeOnDropSentinel for verification.

fn assert_zeroize_on_drop(self)

Asserts that zeroization happens when this value is dropped.

impl<T> Default for RedoubtOption<T>

where T: FastZeroizable + ZeroizeMetadata + ZeroizationProbe + Default,

fn default() -> RedoubtOption<T>

Returns the “default value” for a type.

impl<T> FastZeroizable for RedoubtOption<T>

where T: FastZeroizable + ZeroizeMetadata + ZeroizationProbe,

fn fast_zeroize(&mut self)

Zeroizes the value in place.

impl<T> ZeroizationProbe for RedoubtOption<T>

where T: FastZeroizable + ZeroizeMetadata + ZeroizationProbe,

fn is_zeroized(&self) -> bool

Returns true if the value is zeroized (all bytes are 0).

impl<T> ZeroizeMetadata for RedoubtOption<T>

where T: FastZeroizable + ZeroizeMetadata + ZeroizationProbe,

const CAN_BE_BULK_ZEROIZED: bool = false

Whether this type can be bulk-zeroized with memset.
