    pub fn from_bytes(bytes: &Self::Repr) -> CtOption<Self>;

Associated Types

type Repr: Default + AsRef<[u8]> + AsMut<[u8]>[src]

The encoding of group elements.

The Default implementation is not required to return a valid point encoding. The bound is present to enable encodings to be constructed generically:

let mut encoding = <G as GroupEncoding>::Repr::default();
encoding.as_mut().copy_from_slice(buf);

It is recommended that the default should be the all-zeroes encoding.

Required methods

pub fn from_bytes(bytes: &Self::Repr) -> CtOption<Self>[src]

Attempts to deserialize a group element from its encoding.

pub fn from_bytes_unchecked(bytes: &Self::Repr) -> CtOption<Self>[src]

Attempts to deserialize a group element, not checking if the element is valid.

This is dangerous to call unless you trust the bytes you are reading; otherwise, API invariants may be broken. Please consider using GroupEncoding::from_bytes instead.

pub fn to_bytes(&self) -> Self::Repr[src]

Converts this element into its byte encoding. This may or may not support encoding the identity.
