Struct StdoutSpanParser 

pub struct StdoutSpanParser;

Parser for extracting OTEL spans from container stdout

Implementations

impl StdoutSpanParser

pub fn parse(stdout: &str) -> Result<Vec<SpanData>>

Parse OTEL spans from container stdout

This method extracts JSON-formatted OTEL spans from mixed stdout content (logs, debug output, etc.). Non-JSON lines are silently ignored.

Arguments

• stdout - Container stdout containing OTEL spans and other output

Returns

• Result<Vec<SpanData>> - Extracted spans or error

Example

use clnrm_core::otel::stdout_parser::StdoutSpanParser;

let stdout = r#"
Starting test...
{"name":"test.span","trace_id":"abc123","span_id":"span1","parent_span_id":null,"attributes":{}}
Some log output
{"name":"test.span2","trace_id":"abc123","span_id":"span2","parent_span_id":"span1","attributes":{}}
Done.
"#;

let spans = StdoutSpanParser::parse(stdout).unwrap();
assert_eq!(spans.len(), 2);
