Struct ParserRegistry 

pub struct ParserRegistry { /* private fields */ }

The active set of parsers. Feeds each line to every parser and concatenates their entries. The Vec<Box<dyn CompilationParser>> is the extensibility seam: built-in parsers, plus (CM.6) WASM-contributed ones — a plugin implementing the error-parser world is registered here as one more Box<dyn CompilationParser> and is indistinguishable from a native parser downstream.

Implementations

impl ParserRegistry

pub fn new() -> Self

An empty registry (no parsers). Prefer Self::with_builtins.

pub fn with_builtins() -> Self

The default registry: the built-in cargo/rustc (multi-line) + gnu-style (single-line) parsers.

pub fn register(&mut self, parser: Box<dyn CompilationParser>)

Add a parser to the active set. Order is preserved; each line is fed to parsers in registration order.

CM.6: plugin parsers register before Self::with_builtins’s catch-all would claim a line, but after the format-specific natives. The dedup in Self::feed is first-entry-wins per location, so a plugin that recognises a line rustc also recognises does not displace rustc’s richer entry — and a line only the plugin understands is still its own.

pub fn register_before_catch_all(&mut self, parser: Box<dyn CompilationParser>)

CM.6: register a plugin parser, placed ahead of the catch-all.

with_builtins ends with GeneralParser, whose job is to salvage a file:line:col out of anything. If a plugin registered after it, the catch-all’s thin Info entry would win the dedup for every location the plugin also matched, and the plugin’s severity and message would be silently discarded — the plugin would look like it did nothing.

pub fn feed(&mut self, line: &str) -> Vec<ErrorEntry>

Feed one line to every registered parser and concatenate the entries they complete. Deduplicates by (path, line, col) — the FIRST entry for each location wins. Format-specific parsers register first and produce richer metadata (severity, message); the catch-all [crate::parsers::GeneralParser] registers last and its Info/empty duplicates are silently dropped.

Trait Implementations

impl Default for ParserRegistry

fn default() -> Self

Returns the “default value” for a type.
