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§
Sourcefn from_bytes(bytes: &Self::Repr) -> CtOption<Self>
fn from_bytes(bytes: &Self::Repr) -> CtOption<Self>
Attempts to deserialize a group element from its encoding.
Sourcefn from_bytes_unchecked(bytes: &Self::Repr) -> CtOption<Self>
fn from_bytes_unchecked(bytes: &Self::Repr) -> CtOption<Self>
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.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
