Implementations

impl Parameter

pub fn new_known(value: u64, name: Option<String>) -> Self

Creates a new parameter with a value and an optional name.

pub fn new_named(name: &str) -> Self

Creates a new parameter with a name. This call cannot be used to declare a parameter at compile-time.

pub const fn new_with_static_name(value: u64, name: &'static str) -> Self

Creates a new parameter with a value and a static name. This call can be used to declare a parameter at compile-time.

pub const fn new_static_named(name: &'static str) -> Self

Creates a new parameter with a static name. This call can be used to declare a parameter at compile-time.

pub fn name(&self) -> String

Returns the name of the parameter.

Trait Implementations

fn from_tagged_cbor_data(data: &[u8]) -> Result<Self, Error>

where Self: Sized,

Creates an instance of this type by decoding it from binary encoded tagged CBOR.

fn from_untagged_cbor_data(data: &[u8]) -> Result<Self, Error>

where Self: Sized,

Creates an instance of this type by decoding it from binary encoded untagged CBOR.

impl CBORTaggedEncodable for Parameter

fn untagged_cbor(&self) -> CBOR

Returns the untagged CBOR encoding of this instance.

fn tagged_cbor(&self) -> CBOR

Returns the tagged CBOR encoding of this instance.

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

Returns the tagged value in CBOR binary representation.

impl Clone for Parameter

fn clone(&self) -> Parameter

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Parameter

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

Formats the value using the given formatter.

impl Display for Parameter

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

Formats the value using the given formatter.

impl EnvelopeEncodable for Parameter

fn envelope(self) -> Envelope

impl From<&Parameter> for Parameter

fn from(parameter: &Parameter) -> Self

Converts to this type from the input type.

impl From<&str> for Parameter

fn from(name: &str) -> Self

Converts to this type from the input type.

impl From<Parameter> for CBOR

fn from(value: Parameter) -> Self

Converts to this type from the input type.

impl From<Parameter> for Envelope

fn from(value: Parameter) -> Self

Converts to this type from the input type.

impl From<u64> for Parameter

fn from(value: u64) -> Self

impl Hash for Parameter

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,

impl PartialEq for Parameter

fn eq(&self, other: &Self) -> 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 TryFrom<CBOR> for Parameter

type Error = Error

The type returned in the event of a conversion error.

fn try_from(cbor: CBOR) -> Result<Self, Self::Error>

Performs the conversion.
