Struct Simple 

pub struct Simple(/* private fields */);

A simple value of CBOR major type 7 which has no dedicated variant.

The values 20 to 23 are false, true, null and undefined, and the values 24 to 31 are reserved by RFC 8949, so this wrapper only accepts a number in the range 0 to 19 or 32 to 255.

Example

use cbor_next::Simple;

assert_eq!(Simple::try_from(10).unwrap().value(), 10);
assert!(Simple::try_from(255).is_ok());
assert!(Simple::try_from(24).is_err());
assert!(Simple::try_from(29).is_err());

Implementations

impl Simple

pub fn value(self) -> u8

impl Ord for Simple

fn cmp(&self, other: &Self) -> 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.

where Self: Sized, R: ClampBounds<Self>,

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

Restrict a value to a certain range.

impl PartialEq for Simple

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Simple

fn partial_cmp(&self, other: &Self) -> 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

impl StructuralPartialEq for Simple

impl TryFrom<u8> for Simple

fn try_from(value: u8) -> Result<Self, Self::Error>

Errors

If the number is between 20 and 31, which RFC 8949 either assigns to a dedicated data item or reserves

type Error = Error

The type returned in the event of a conversion error.
