Crate logdive_core 

logdive-core

Core library for logdive — structured log parsing, SQLite-backed indexing, and a hand-written query engine.

This crate is pure library code with no I/O side effects at the module level. It is consumed by the logdive CLI binary and the logdive-api HTTP server binary.

v0.2.0 introduced multi-format ingestion: JSON, logfmt, and plain text. See parsers for the format-specific parsers and the format-aware parse_line dispatcher.

v0.2.0 also introduces follow (Unix-only), which provides FileTailer for tracking a growing file and detecting log rotation and truncation. Used by the CLI’s --follow flag.

Modules

entry

The LogEntry type — a single parsed log line.

error

Unified error type for logdive-core.

executor

Query executor: translate a QueryNode into parameterized SQL, run it against the index, and reconstruct LogEntry values from the result rows.

follow

File tailing for follow mode (--follow).

indexer

SQLite-backed index for ingested log entries.

parsers

Format-aware line parsing for log ingestion.

query

Query language: tokenizer, AST, and recursive descent parser.
