Type Alias ConsumedResult

pub type ConsumedResult<O, I> = FastResult<O, <I as StreamOnce>::Error>;

A Result type which has the consumed status flattened into the result. Conversions to and from std::result::Result can be done using result.into() or From::from(result)

Aliased Type

enum ConsumedResult<O, I> {
    ConsumedOk(O),
    EmptyOk(O),
    ConsumedErr(<I as StreamOnce>::Error),
    EmptyErr(Tracked<<I as StreamOnce>::Error>),
}

Variants

ConsumedOk(O)

EmptyOk(O)

ConsumedErr(<I as StreamOnce>::Error)

EmptyErr(Tracked<<I as StreamOnce>::Error>)

Trait Implementations

impl<T: Clone, E: Clone> Clone for FastResult<T, E>

fn clone(&self) -> FastResult<T, E>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug, E: Debug> Debug for FastResult<T, E>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<O, E> From<Result<(O, Consumed<()>), Consumed<Tracked<E>>>> for FastResult<O, E>

fn from(result: ParseResult2<O, E>) -> FastResult<O, E>

Converts to this type from the input type.

impl<O, E> Into<Result<(O, Consumed<()>), Consumed<Tracked<E>>>> for FastResult<O, E>

fn into(self) -> ParseResult2<O, E>

Converts this type into the (usually inferred) input type.

impl<T, E> Into<Result<Consumed<T>, Consumed<Tracked<E>>>> for FastResult<T, E>

fn into(self) -> Result<Consumed<T>, Consumed<Tracked<E>>>

Converts this type into the (usually inferred) input type.

impl<T: PartialEq, E: PartialEq> PartialEq for FastResult<T, E>

fn eq(&self, other: &FastResult<T, E>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
