Struct DiagnosticsExtractor 

pub struct DiagnosticsExtractor { /* private fields */ }

Stateless, Send + Sync diagnostics extractor.

Each task execution gets one instance (shared between stdout and stderr streams via Arc). All extracted issues receive the same marker and source so they can be cleared together when the task reruns.

Implementations

impl DiagnosticsExtractor

pub fn new(marker: impl Into<String>, source: impl Into<String>) -> Self

Construct a new extractor.

• marker — issue registry marker, usually "task:{queue}:{target}".
• source — human-readable tag for the registry (e.g. "build").

pub fn extract_from_line(&self, line: &StyledLine) -> Vec<NewIssue>

Extract zero or more NewIssues from a single styled output line.

The plain text content of the line is used; ANSI styling is ignored. Returns an empty Vec if the line matches no known pattern.

pub fn extract_from_str(&self, text: &str) -> Vec<NewIssue>

Extract zero or more NewIssues from a plain text line.

Equivalent to Self::extract_from_line but accepts a &str directly, useful when the caller already has plain text (e.g. from a terminal PTY output buffer where ANSI codes have already been stripped by the VT100 parser).

pub fn try_rustc_header(&self, text: &str) -> Option<(Severity, String)>

Try to match a rustc/cargo severity header line such as error[E0425]: cannot find value \x`orwarning: unused variable`.

Returns (severity, message) if matched, None otherwise.

pub fn try_rustc_arrow(&self, text: &str) -> Option<(PathBuf, usize, usize)>

Try to match a rustc/cargo source-location line such as --> src/main.rs:5:10.

Returns (path, line, col) if matched, None otherwise.

pub fn make_issue( &self, severity: Severity, message: String, path: Option<PathBuf>, line: Option<usize>, column: Option<usize>, ) -> NewIssue

Build a NewIssue from individual components.

line and column are 1-based; they are converted to 0-based [Position] internally.
