Struct OptionalHash 

pub struct OptionalHash {
    pub hash: Option<Vec<u8>>,
}

Fields

hash: Option<Vec<u8>>

Implementations

impl OptionalHash

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

Returns the value of hash, or the default value if hash is unset.

Trait Implementations

impl Clone for OptionalHash

fn clone(&self) -> OptionalHash

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptionalHash

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

Formats the value using the given formatter.

impl Default for OptionalHash

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for OptionalHash

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<D> From<Option<Hash<D>>> for OptionalHash

where D: SupportedDigest,

fn from(value: Option<Hash<D>>) -> Self

Converts to this type from the input type.

impl Message for OptionalHash

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for OptionalHash

fn eq(&self, other: &OptionalHash) -> 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 Serialize for OptionalHash

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

where S: Serializer,

Serialize this value into the given Serde serializer.

impl<D> TryFrom<OptionalHash> for Option<Hash<D>>

where D: SupportedDigest,

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: OptionalHash) -> Result<Self, Self::Error>

Performs the conversion.
