High-level encoding functions to write values in their canonical format.

Provided methods

pub fn encode_u64(self, value: u64) -> Self::Output

Encode an unsigned integer of at most 64 bit.

Also to be used for smaller unsigned integers:

use cbor_data::{CborBuilder, Encoder};

let short = 12345u16;
let cbor = CborBuilder::default().encode_u64(short.into());

pub fn encode_i64(self, value: i64) -> Self::Output

Encode a signed integer of at most 64 bit.

Also to be used for smaller signed integers:

use cbor_data::{CborBuilder, Encoder};

let short = -12345i16;
let cbor = CborBuilder::default().encode_i64(short.into());

pub fn encode_f64(self, value: f64) -> Self::Output

Encode a floating-point number of at most 64 bit.

Also to be used for smaller formats:

use cbor_data::{CborBuilder, Encoder};

let single = -3.14f32;
let cbor = CborBuilder::default().encode_f64(single.into());

pub fn encode_array<F, T>(self, f: F) -> (Self::Output, T) where
    F: FnMut(&mut ArrayWriter<'_>) -> T, 

Write an array that is then filled by the provided closure using the passed builder.

see trait Encoder for usage examples

pub fn encode_dict<F, T>(self, f: F) -> (Self::Output, T) where
    F: FnMut(&mut DictWriter<'_>) -> T, 

Write a dict that is then filled by the provided closure using the passed builder.
