Trait Implementations

source

impl<G: AffineCurve> CanonicalDeserialize for PedersenCommitment<G>

source

fn deserialize<R: Read>(reader: R) -> Result<Self, SerializationError>

Reads Self from reader.

source

fn deserialize_uncompressed<R: Read>(
reader: R
) -> Result<Self, SerializationError>

Reads Self from reader without compression.

source

fn deserialize_unchecked<R: Read>(reader: R) -> Result<Self, SerializationError>

Reads self from reader without compression, and without performing validity checks. Should be used only when the input is trusted. Read more

source

impl<G: AffineCurve> CanonicalSerialize for PedersenCommitment<G>

source

fn serialize<W: Write>(&self, writer: W) -> Result<(), SerializationError>

Serializes self into writer. It is left up to a particular type for how it strikes the serialization efficiency vs compression tradeoff. For standard types (e.g. bool, lengths, etc.) typically an uncompressed form is used, whereas for algebraic types compressed forms are used. Read more

fn serialized_size(&self) -> usize

source

fn serialize_uncompressed<W: Write>(
&self,
writer: W

source

fn serialize_unchecked<W: Write>(
&self,
writer: W
) -> Result<(), SerializationError>

Serializes self into writer without compression, and without performing validity checks. Should be used only when there is no danger of adversarial manipulation of the output. Read more
