Struct Digest

pub struct Digest {
    pub logs: Vec<DigestItem>,
}

Generic header digest.

Fields

logs: Vec<DigestItem>

A list of logs in the digest.

Implementations

impl Digest

pub fn logs(&self) -> &[DigestItem]

Get reference to all digest items.

pub fn push(&mut self, item: DigestItem)

Push new digest item.

pub fn pop(&mut self) -> Option<DigestItem>

Pop a digest item.

pub fn log<T: ?Sized, F: Fn(&DigestItem) -> Option<&T>>( &self, predicate: F, ) -> Option<&T>

Get reference to the first digest item that matches the passed predicate.

pub fn convert_first<T, F: Fn(&DigestItem) -> Option<T>>( &self, predicate: F, ) -> Option<T>

Get a conversion of the first digest item that successfully converts using the function.

Trait Implementations

impl Clone for Digest

fn clone(&self) -> Digest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Digest

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

Formats the value using the given formatter.

impl Decode for Digest

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy, ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Default for Digest

fn default() -> Digest

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Digest

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for Digest

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

Convert self to a slice and append it to the destination.

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

Convert self to an owned vector.

fn using_encoded<__CodecOutputReturn, __CodecUsingEncodedCallback: FnOnce(&[u8]) -> __CodecOutputReturn>( &self, f: __CodecUsingEncodedCallback, ) -> __CodecOutputReturn

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl PartialEq for Digest

fn eq(&self, other: &Digest) -> 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 Digest

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TypeInfo for Digest

type Identity = Digest

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl EncodeLike for Digest

impl Eq for Digest
