Struct kparse::Track

pub struct Track;

Central struct for tracking.

• Create a TrackProvider with Track::new_tracker()

• Create a matching span with new_span(). Switches between debug and release mode, and tracking is only active in debug mode.

• Create a SourceStr/SourceBytes for row/column information.

• Call the actual tracking functions:

  • Track.enter(), Track.ok(), Track.err(), …

Implementations

impl Track

pub fn new_tracker<C, I>() -> StdTracker<C, I>where C: Code, I: Clone + Debug + AsBytes + InputTake + InputLength + InputIter,

Provider/Container for tracking data.

pub fn new_span<'s, C, I>( provider: &'s impl TrackProvider<C, I>, text: I ) -> LocatedSpan<I, DynTrackProvider<'s, C, I>>where C: Code, I: Clone + Debug + AsBytes + InputTake + InputLength + InputIter + 's,

Create a tracking span for the given text and TrackProvider.

pub fn source_str(text: &str) -> SourceStr<'_>

Create a source text map for the given text.

pub fn source_bytes(text: &[u8]) -> SourceBytes<'_>

Create a source text map for the given text.

pub fn ok<C, I, O, E>( &self, rest: I, input: I, value: O ) -> Result<(I, O), Err<E>>where C: Code, I: Clone + Debug + TrackedSpan<C> + InputTake + InputLength + InputIter, E: KParseError<C, I> + Debug,

Creates an Ok() Result from the parameters and tracks the result.

pub fn err<C, I, O, E>( &self, err: E ) -> Result<(I, O), Err<<E as ErrOrNomErr>::WrappedError>>where C: Code, I: Clone + Debug + TrackedSpan<C> + InputTake + InputLength + InputIter, E: KParseError<C, I> + ErrOrNomErr + Debug,

Tracks the error and creates a Result.

pub fn ok_section<C, I>(&self, rest: I, input: I)where C: Code, I: TrackedSpan<C>,

When multiple Context.enter() calls are used within one function (to denote some separation), this can be used to exit such a compartment with an ok track.

pub fn err_section<C, I, E>(&self, err: &E)where C: Code, I: Clone + Debug + TrackedSpan<C> + InputTake + InputLength + InputIter, E: KParseError<C, I> + Debug,

When multiple Context.enter() calls are used within one function (to denote some separation), this can be used to exit such a compartment with an ok track.

pub fn enter<C, I>(&self, func: C, span: I)where C: Code, I: TrackedSpan<C>,

Enter a parser function.

pub fn debug<C, I>(&self, span: I, debug: String)where C: Code, I: TrackedSpan<C>,

Track some debug info.

pub fn info<C, I>(&self, span: I, info: &'static str)where C: Code, I: TrackedSpan<C>,

Track some other info.

pub fn warn<C, I>(&self, span: I, warn: &'static str)where C: Code, I: TrackedSpan<C>,

Track some warning.
