Struct std_logger_parser::Parser [−][src]
A struct to parse logfmt formatted logs.
See the example below for usage.
Notes
The parser assumses the log lines are mostly correct. This means it will loosely check values but isn’t too strict about it.
If this parser returns an error it will skip the problematic line and continue with the next one. Note however that if a problem exists in multi-line log message the records returned after might be invalid.
Examples
The API is simple, just call parse
in a for loop.
use std_logger_parser::parse; let logs = /* Open some log file, anything that implements `io::Read`. */ for record in parse(logs) { let record = record?; println!("parsed a record: {:?}", record); }
