Function from_slice 

pub fn from_slice(
    data: &[u8],
) -> Result<(Vec<Vec<SpanSlice<'_>>>, usize), DecodeError>

Decodes a slice of bytes into a Vec<Vec<SpanSlice>> object. The resulting spans have the same lifetime as the initial buffer.

Arguments

• data - A slice of bytes containing the encoded data. Bytes are expected to be encoded msgpack data containing a list of a list of v05 spans.

Returns

• Ok(Vec<Vec<SpanSlice>>) - A vector of decoded Vec<SpanSlice> objects if successful.
• Err(DecodeError) - An error if the decoding process fails.

Errors

This function will return an error if:

• The array length for trace count or span count cannot be read.
• Any span cannot be decoded.

Examples

use libdd_tinybytes;
use libdd_trace_utils::msgpack_decoder::v05::from_slice;
use rmp_serde::to_vec;
use std::collections::HashMap;

let data = (
    vec!["".to_string()],
    vec![vec![(
        0,
        0,
        0,
        1,
        2,
        3,
        4,
        5,
        6,
        HashMap::<u32, u32>::new(),
        HashMap::<u32, f64>::new(),
        0,
    )]],
);
let encoded_data = to_vec(&data).unwrap();
let encoded_data_as_tinybytes = libdd_tinybytes::Bytes::from(encoded_data);
let (decoded_traces, _payload_size) =
    from_slice(&encoded_data_as_tinybytes).expect("Decoding failed");

assert_eq!(1, decoded_traces.len());
assert_eq!(1, decoded_traces[0].len());
let decoded_span = &decoded_traces[0][0];
assert_eq!("", decoded_span.name);
