Trait Implementations

impl AsMut<[u64]> for FrRepr

fn as_mut(&mut self) -> &mut [u64]

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<[u64]> for FrRepr

fn as_ref(&self) -> &[u64]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for FrRepr

fn clone(&self) -> FrRepr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FrRepr

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

Formats the value using the given formatter.

impl Default for FrRepr

fn default() -> FrRepr

Returns the “default value” for a type.

impl Display for FrRepr

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

Formats the value using the given formatter.

impl From<Fr> for FrRepr

fn from(e: Fr) -> FrRepr

Converts to this type from the input type.

impl From<u64> for FrRepr

fn from(val: u64) -> FrRepr

Converts to this type from the input type.

impl Ord for FrRepr

fn cmp(&self, other: &FrRepr) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for FrRepr

fn eq(&self, other: &FrRepr) -> 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 PartialOrd for FrRepr

fn partial_cmp(&self, other: &FrRepr) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl PrimeFieldRepr for FrRepr

fn is_odd(&self) -> bool

Returns true iff this number is odd.

fn is_even(&self) -> bool

Returns true iff this number is even.

fn is_zero(&self) -> bool

Returns true iff this number is zero.

fn shr(&mut self, n: u32)

Performs a rightwise bitshift of this number by some amount.

fn div2(&mut self)

Performs a rightwise bitshift of this number, effectively dividing it by 2.

fn mul2(&mut self)

Performs a leftwise bitshift of this number, effectively multiplying it by 2. Overflow is ignored.

fn shl(&mut self, n: u32)

Performs a leftwise bitshift of this number by some amount.

fn num_bits(&self) -> u32

Compute the number of bits needed to encode this number. Always a multiple of 64.

fn add_nocarry(&mut self, other: &FrRepr)

Add another representation to this one.

fn sub_noborrow(&mut self, other: &FrRepr)

Subtract another represetation from this one.

fn write_be<W>(&self, writer: W) -> Result<(), Error>

where W: Write,

Writes this PrimeFieldRepr as a big endian integer.

fn read_be<R>(&mut self, reader: R) -> Result<(), Error>

where R: Read,

Reads a big endian integer into this representation.

fn write_le<W>(&self, writer: W) -> Result<(), Error>

where W: Write,

Writes this PrimeFieldRepr as a little endian integer.

fn read_le<R>(&mut self, reader: R) -> Result<(), Error>

where R: Read,

Reads a little endian integer into this representation.

impl Zeroize for FrRepr

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
