Struct Scalar 

pub struct Scalar { /* private fields */ }

Scalar field representation with up to 256 bits.

This is agnostic to the curve choice and no canonical encoding assumption is involved.

Implementations

impl Scalar

pub const LEN: usize = 32usize

Fixed serialized length

Trait Implementations

impl AsRef<[u8]> for Scalar

fn as_ref(&self) -> &[u8]

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

impl Clone for Scalar

fn clone(&self) -> Scalar

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Scalar

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

Formats the value using the given formatter.

impl DecodableElement for Scalar

fn try_from_buffer_in_place<'b>( &mut self, ctx: &DecoderContext<'_>, buf: &'b [u8], ) -> Result<()>

Deserialize the type from a given buffer

fn try_from_buffer<'b>(ctx: &DecoderContext<'_>, buf: &'b [u8]) -> Result<Self>

Create a new instance of the type from the provided buffer

fn try_decode_in_place<'a, 'b>( &mut self, ctx: &DecoderContext<'a>, buf: &'b [u8], ) -> Result<&'b [u8]>

Write an element from the buffer, and return the remainder bytes

fn try_decode<'a, 'b>( ctx: &DecoderContext<'a>, buf: &'b [u8], ) -> Result<(Self, &'b [u8])>

Write an element from the buffer, and return the remainder bytes

fn try_from_reader<R>(ctx: &DecoderContext<'_>, reader: R) -> Result<Self>

where R: Read,

Fetch a new element from a context

impl Default for Scalar

fn default() -> Scalar

Returns the “default value” for a type.

impl Deref for Scalar

type Target = [u8; 32]

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for Scalar

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl Element for Scalar

fn len(ctx: &Config) -> usize

Serializable length

fn validate(&self, _preamble: &Preamble) -> Result<()>

Perform the internal validations of the associated element

fn validate_buffer(config: &Config, buffer: &[u8]) -> Result<()>

Assert the buffer is big enough to store the type

impl EncodableElement for Scalar

fn to_buffer(&self, ctx: &mut EncoderContext, buf: &mut [u8])

Write the type into the buffer.

fn to_vec(&self, ctx: &mut EncoderContext) -> Vec<u8>

Serialize the object into a bytes array.

fn encode<'a>( &self, ctx: &mut EncoderContext, buf: &'a mut [u8], ) -> &'a mut [u8]

Read an element into the buffer, returning the remainder bytes

fn try_to_writer<W>(&self, writer: W, ctx: &mut EncoderContext) -> Result<usize>

where W: Write,

Send the bytes representation of an element to a writer

impl From<[u8; 32]> for Scalar

fn from(scalar: [u8; 32]) -> Self

Converts to this type from the input type.

impl Hash for Scalar

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

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 Ord for Scalar

fn cmp(&self, other: &Scalar) -> 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 Scalar

fn eq(&self, other: &Scalar) -> 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 Scalar

fn partial_cmp(&self, other: &Scalar) -> 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.
