Struct UnwrapMut 

pub struct UnwrapMut<'r, R>(pub &'r mut R)
where
    R: TryRngCore + ?Sized;

Wrapper around TryRngCore implementation which implements RngCore by panicking on potential errors.

Tuple Fields

0: &'r mut R

Implementations

impl<'r, R> UnwrapMut<'r, R>

where R: TryRngCore + ?Sized,

pub fn re<'b>(&'b mut self) -> UnwrapMut<'b, R>

where 'r: 'b,

Reborrow with a new lifetime

Rust allows references like &T or &mut T to be “reborrowed” through coercion: essentially, the pointer is copied under a new, shorter, lifetime. Until rfcs#1403 lands, reborrows on user types require a method call.

Trait Implementations

impl<'r, R> Debug for UnwrapMut<'r, R>

where R: Debug + TryRngCore + ?Sized,

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

Formats the value using the given formatter.

impl<'r, R> Hash for UnwrapMut<'r, R>

where R: Hash + TryRngCore + ?Sized,

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'r, R> PartialEq for UnwrapMut<'r, R>

where R: PartialEq + TryRngCore + ?Sized,

fn eq(&self, other: &UnwrapMut<'r, R>) -> 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<R> RngCore for UnwrapMut<'_, R>

where R: TryRngCore + ?Sized,

fn next_u32(&mut self) -> u32

Return the next random u32.

fn next_u64(&mut self) -> u64

Return the next random u64.

fn fill_bytes(&mut self, dst: &mut [u8])

Fill dest with random data.

impl<R> CryptoRng for UnwrapMut<'_, R>

where R: TryCryptoRng + ?Sized,

impl<'r, R> Eq for UnwrapMut<'r, R>

where R: Eq + TryRngCore + ?Sized,

impl<'r, R> StructuralPartialEq for UnwrapMut<'r, R>

where R: TryRngCore + ?Sized,
