Trait TrackResult

pub trait TrackResult<C, I>
where
    C: Code,
    I: Clone + Debug + TrackedSpan<C> + InputTake + InputLength + InputIter + AsBytes,
{
    // Required methods
    fn track(self) -> Self;
    fn track_as(self, code: C) -> Self;
}

This is an extension trait for nom-Results.

This is for inline tracking of parser results.

let (rest, h0) = nom_header(input).track_as(APCHeader)?;
let (rest, _) = nom_tag_plan(rest).track_as(APCPlan)?;
let (rest, plan) = token_name(rest).track()?;
let (rest, h1) = nom_header(rest).track_as(APCHeader)?;

Required Methods

fn track(self) -> Self

Track an Err() result.

fn track_as(self, code: C) -> Self

Track an Err() result and modify the error code in one go.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types

impl<C, I, O, E> TrackResult<C, I> for Result<(I, O), Err<E>>

where C: Code, I: Clone + Debug + TrackedSpan<C> + InputTake + InputLength + InputIter + AsBytes, E: Debug, Err<E>: KParseError<C, I>,

fn track(self) -> Self

Tracks the result if it is an error.

fn track_as(self, code: C) -> Self

Changes the error code and tracks the result.
