Implementations

impl Header

pub fn encoded_hash(&self) -> Hash

Returns a hash of an encoded header.

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Header

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

Formats the value using the given formatter.

impl Decode for Header

fn try_default() -> Result<Self, DecodeError>

Try to decode from a missing/null/undefined value.

fn try_from_cbor_value(value: Value) -> Result<Self, DecodeError>

Try to decode from a given CBOR value.

fn try_from_cbor_value_default(value: Value) -> Result<Self, DecodeError>

where Self: Sized,

Try to decode from a given CBOR value, calling try_default in case the value is null or undefined.

impl Default for Header

fn default() -> Header

Returns the “default value” for a type.

impl Encode for Header

fn into_cbor_value(self) -> Value

Encode the type into a CBOR Value.

fn is_empty(&self) -> bool

Whether the value is equal to the empty value for the type.

impl EncodeAsMap for Header

fn into_cbor_value_map(self) -> Value

where Self: Sized,

Encode the type into a CBOR Map.

fn into_cbor_map(self) -> Vec<(Value, Value)>

where Self: Sized,

Encode the type into a CBOR Map, returning the map items.

impl Hash for Header

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Header

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for Header
