}

Possible CBOR values.

Variants

Unsigned(u64)

Unsigned integer value (uint).

Negative(i64)

Signed integer value (nint). Only 63 bits of information are used here.

ByteString(Vec<u8>)

Byte string (bstr).

TextString(String)

Text string (tstr).

Array(Vec<Value>)

Array/tuple of values.

Map(Vec<(Value, Value)>)

Map of key-value pairs.

Tag(u64, Box<Value>)

Tagged value.

Simple(SimpleValue)

Simple value.

Implementations

impl Value

pub fn integer(int: i64) -> Value

Create an appropriate CBOR integer value (uint/nint). For simplicity, this only takes i64. Construct directly for the last bit.

pub fn bool_value(b: bool) -> Value

Create a CBOR boolean simple value.

pub fn type_label(&self) -> u8

Return the major type for the Value.

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl From<&[u8]> for Value

fn from(bytes: &[u8]) -> Self

Converts to this type from the input type.

impl From<&str> for Value

fn from(text: &str) -> Self

Converts to this type from the input type.

impl From<String> for Value

fn from(text: String) -> Self

Converts to this type from the input type.

impl From<Vec<(Value, Value)>> for Value

fn from(map: Vec<(Value, Value)>) -> Self

Converts to this type from the input type.

impl From<Vec<u8>> for Value

fn from(bytes: Vec<u8>) -> Self

Converts to this type from the input type.

impl From<bool> for Value

fn from(b: bool) -> Self

Converts to this type from the input type.

impl From<i32> for Value

fn from(i: i32) -> Self

Converts to this type from the input type.

impl From<i64> for Value

fn from(i: i64) -> Self

Converts to this type from the input type.

impl From<u64> for Value

fn from(unsigned: u64) -> Self

Converts to this type from the input type.

impl Ord for Value

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Value

fn eq(&self, other: &Value) -> 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 PartialOrd for Value

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
