Struct exonum::blockchain::AdditionalHeaders

pub struct AdditionalHeaders { /* fields omitted */ }

Expandable set of headers allowed to be added to the block.

In a serialized form, headers are represented as a sequence of pairs, in which first element is a string (header name), and the second element is a byte sequence (deserialization format for which depends on the header name).

Methods

impl AdditionalHeaders

pub fn new() -> Self

New instance of AdditionalHeaders.

pub fn insert<K: BlockHeaderKey>(&mut self, value: K::Value)

Insert new header to the map.

pub fn get<K: BlockHeaderKey>(&self) -> Option<&[u8]>

Get header from the map.

Trait Implementations

impl Clone for AdditionalHeaders

fn clone(&self) -> AdditionalHeaders

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AdditionalHeaders

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

impl Eq for AdditionalHeaders

impl Ord for AdditionalHeaders

fn cmp(&self, other: &AdditionalHeaders) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<AdditionalHeaders> for AdditionalHeaders

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

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

fn ne(&self, other: &AdditionalHeaders) -> bool

This method tests for !=.

impl PartialOrd<AdditionalHeaders> for AdditionalHeaders

fn partial_cmp(&self, other: &AdditionalHeaders) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &AdditionalHeaders) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &AdditionalHeaders) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &AdditionalHeaders) -> bool
