Struct AppHash

pub struct AppHash(/* private fields */);

AppHash is usually a SHA256 hash, but in reality it can be any kind of data

Implementations

impl AppHash

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

Return the hash bytes as a byte slice.

pub fn from_hex_upper(s: &str) -> Result<Self, Error>

Decode a Hash from upper-case hexadecimal

Trait Implementations

impl AsRef<[u8]> for AppHash

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

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for AppHash

fn clone(&self) -> AppHash

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AppHash

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

Formats the value using the given formatter.

impl Default for AppHash

fn default() -> AppHash

Returns the “default value” for a type.

impl Display for AppHash

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

Formats the value using the given formatter.

impl From<AppHash> for Bytes

fn from(value: AppHash) -> Self

Converts to this type from the input type.

impl From<AppHash> for Vec<u8>

fn from(value: AppHash) -> Self

Converts to this type from the input type.

impl FromStr for AppHash

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Error>

Parses a string s to return a value of this type.

impl PartialEq for AppHash

fn eq(&self, other: &AppHash) -> 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 Protobuf<Vec<u8>> for AppHash

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

where B: BufMut,

Encode into a buffer in Protobuf format.

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

where B: BufMut,

Encode with a length-delimiter to a buffer in Protobuf format.

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

where B: Buf,

Constructor that attempts to decode an instance from a buffer.

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

where B: Buf,

Constructor that attempts to decode a length-delimited instance from the buffer.

fn encoded_len(self) -> usize

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

fn encode_vec(self) -> Vec<u8>

Encodes into a Protobuf-encoded Vec<u8>.

fn decode_vec(v: &[u8]) -> Result<Self, Error>

Constructor that attempts to decode a Protobuf-encoded instance from a Vec<u8> (or equivalent).

fn encode_length_delimited_vec(self) -> Vec<u8>

Encode with a length-delimiter to a Vec<u8> Protobuf-encoded message.

fn decode_length_delimited_vec(v: &[u8]) -> Result<Self, Error>

Constructor that attempts to decode a Protobuf-encoded instance with a length-delimiter from a Vec<u8> or equivalent.

impl TryFrom<Bytes> for AppHash

type Error = Error

The type returned in the event of a conversion error.

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

Performs the conversion.

impl TryFrom<Vec<u8>> for AppHash

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: Vec<u8>) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for AppHash
