Struct cjdns_crypto::sign::ed25519::Seed

#[must_use]pub struct Seed(pub [u8; 32]);

Seed that can be used for keypair generation

The Seed is used by keypair_from_seed() to generate a secret and public signature key.

When a Seed goes out of scope its contents will be zeroed out

Implementations

impl Seed

pub fn from_slice(bs: &[u8]) -> Option<Seed>

from_slice() creates an object from a byte slice

This function will fail and return None if the length of the byte-slice isn't equal to the length of the object

Trait Implementations

impl AsRef<[u8]> for Seed

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

Performs the conversion.

impl Clone for Seed

pub fn clone(&self) -> Seed

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Seed

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Seed

pub fn deserialize<D>(
    deserializer: D
) -> Result<Seed, <D as Deserializer<'de>>::Error> where
    D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Drop for Seed

pub fn drop(&mut self)

Executes the destructor for this type.

impl Eq for Seed

impl Index<Range<usize>> for Seed

Allows a user to access the byte contents of an object as a slice.

WARNING: it might be tempting to do comparisons on objects by using x[a..b] == y[a..b]. This will open up for timing attacks when comparing for example authenticator tags. Because of this only use the comparison functions exposed by the sodiumoxide API.

type Output = [u8]

The returned type after indexing.

pub fn index(&self, _index: Range<usize>) -> &[u8]

Performs the indexing (container[index]) operation.

impl Index<RangeFrom<usize>> for Seed

Allows a user to access the byte contents of an object as a slice.

WARNING: it might be tempting to do comparisons on objects by using x[a..] == y[a..]. This will open up for timing attacks when comparing for example authenticator tags. Because of this only use the comparison functions exposed by the sodiumoxide API.

type Output = [u8]

The returned type after indexing.

pub fn index(&self, _index: RangeFrom<usize>) -> &[u8]

Performs the indexing (container[index]) operation.

impl Index<RangeFull> for Seed

Allows a user to access the byte contents of an object as a slice.

WARNING: it might be tempting to do comparisons on objects by using x[] == y[]. This will open up for timing attacks when comparing for example authenticator tags. Because of this only use the comparison functions exposed by the sodiumoxide API.

type Output = [u8]

The returned type after indexing.

pub fn index(&self, _index: RangeFull) -> &[u8]

Performs the indexing (container[index]) operation.

impl Index<RangeTo<usize>> for Seed

Allows a user to access the byte contents of an object as a slice.

WARNING: it might be tempting to do comparisons on objects by using x[..b] == y[..b]. This will open up for timing attacks when comparing for example authenticator tags. Because of this only use the comparison functions exposed by the sodiumoxide API.

type Output = [u8]

The returned type after indexing.

pub fn index(&self, _index: RangeTo<usize>) -> &[u8]

Performs the indexing (container[index]) operation.

impl PartialEq<Seed> for Seed

pub fn eq(&self, other: &Seed) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Serialize for Seed

pub fn serialize<S>(
    &self,
    serializer: S
) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error> where
    S: Serializer, 

Serialize this value into the given Serde serializer.
