Enum ParseOutcome 

pub enum ParseOutcome<T, E> {
    Done,
    Ok(T),
    Err(E),
}

Tri-state parse result for statement-oriented parser APIs.

Mirrors C parser return codes:

• ParseOutcome::Done -> SYNTAQLITE_PARSE_DONE
• ParseOutcome::Ok -> SYNTAQLITE_PARSE_OK
• ParseOutcome::Err -> SYNTAQLITE_PARSE_ERROR

Variants

Done

No more statements/results are available.

Ok(T)

A statement parsed successfully.

Err(E)

A statement parsed with an error.

Implementations

impl<T, E> ParseOutcome<T, E>

pub fn transpose(self) -> Result<Option<T>, E>

Convert into Result<Option<T>, E> for ?-friendly control flow.

Errors

Returns Err(e) when the outcome is ParseOutcome::Err.

pub fn map<U>(self, f: impl FnOnce(T) -> U) -> ParseOutcome<U, E>

Map the Ok(T) payload.

pub fn map_err<F>(self, f: impl FnOnce(E) -> F) -> ParseOutcome<T, F>

Map the Err(E) payload.

Trait Implementations

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

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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

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

Formats the value using the given formatter.

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

fn eq(&self, other: &ParseOutcome<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.
