The actual data writing methods of DictBuilder.

Required methods

pub fn write_pos(&mut self, key: &str, value: u64, tag: Option<u64>)[src]

Write a unsigned value of up to 64 bits.

pub fn write_neg(&mut self, key: &str, value: u64, tag: Option<u64>)[src]

Write a negative value of up to 64 bits — the represented number is -1 - value.

pub fn write_bytes(&mut self, key: &str, value: &[u8], tag: Option<u64>)[src]

Write the given slice as a definite size byte string.

pub fn write_str(&mut self, key: &str, value: &str, tag: Option<u64>)[src]

Write the given slice as a definite size string.

pub fn write_bool(&mut self, key: &str, value: bool, tag: Option<u64>)[src]

pub fn write_null(&mut self, key: &str, tag: Option<u64>)[src]

pub fn write_undefined(&mut self, key: &str, tag: Option<u64>)[src]

pub fn write_lit(&mut self, key: &str, value: Literal, tag: Option<u64>)[src]

pub fn write_array_rec(
    &mut self,
    key: &str,
    tag: Option<u64>,
    f: &mut dyn FnMut(&mut dyn WriteToArray)
)[src]

Write a nested array using the given closure that receives an array builder.

This method is very useful for recursively building a CBOR structure without statically known recursion limit, avoiding infinite type errors.

use cbor_data::{CborBuilder, WriteToArray, WriteToDict};

let mut cbor = CborBuilder::default().write_dict(None);
cbor.write_array_rec("x", None, &mut |builder| {
    builder.write_pos(42, None);
});
let cbor = cbor.finish();

assert_eq!(cbor.as_slice(), vec![0xbfu8, 0x61, b'x', 0x9f, 0x18, 42, 0xff, 0xff]);

pub fn write_dict_rec(
    &mut self,
    key: &str,
    tag: Option<u64>,
    f: &mut dyn FnMut(&mut dyn WriteToDict)
)[src]

Write a nested dict using the given closure that receives an dict builder.

This method is very useful for recursively building a CBOR structure without statically known recursion limit, avoiding infinite type errors.

use cbor_data::{CborBuilder, WriteToArray, WriteToDict};

let mut cbor = CborBuilder::default().write_dict(None);
cbor.write_dict_rec("x", None, &mut |builder| {
    builder.write_pos("y", 42, None);
});
let cbor = cbor.finish();

assert_eq!(cbor.as_slice(), vec![0xbfu8, 0x61, b'x', 0xbf, 0x61, b'y', 0x18, 42, 0xff, 0xff]);
