Struct TupleParser 

pub struct TupleParser<'doc> { /* private fields */ }

Helper for parsing tuple types from Eure documents.

Provides both sequential access via next() and random access via get(). Use finish() to verify all elements were consumed.

Example

let mut tuple = ctx.parse_tuple()?;
let first: String = tuple.next()?;
let second: i32 = tuple.next()?;
tuple.finish()?; // Ensures no extra elements

Implementations

impl<'doc> TupleParser<'doc>

pub fn node_id(&self) -> NodeId

Get the node ID being parsed.

pub fn next<T>(&mut self) -> Result<T, T::Error>

where T: FromEure<'doc>, T::Error: From<ParseError>,

Get the next element, advancing the position.

Returns ParseErrorKind::MissingField if no more elements.

pub fn next_with<T>(&mut self, parser: T) -> Result<T::Output, T::Error>

where T: DocumentParser<'doc>, T::Error: From<ParseError>,

Get the next element using a custom parser, advancing the position.

pub fn next_via<M, T>(&mut self) -> Result<T, M::Error>

where M: FromEure<'doc, T>, M::Error: From<ParseError>,

Get the next element using a marker type, advancing the position.

pub fn get<T>(&self, index: usize) -> Result<T, T::Error>

where T: FromEure<'doc>, T::Error: From<ParseError>,

Get the element at a specific index without advancing position.

Returns ParseErrorKind::MissingField if the index is out of bounds.

pub fn get_with<T>( &self, index: usize, parser: T, ) -> Result<T::Output, T::Error>

where T: DocumentParser<'doc>, T::Error: From<ParseError>,

Get the element at a specific index using a custom parser.

pub fn get_via<M, T>(&self, index: usize) -> Result<T, M::Error>

where M: FromEure<'doc, T>, M::Error: From<ParseError>,

Get the element at a specific index using a marker type.

pub fn remaining(&self) -> usize

Get the number of remaining elements.

pub fn finish(self) -> Result<(), ParseError>

Verify all elements were consumed.

Returns ParseErrorKind::UnexpectedTupleLength if elements remain.

pub fn expect_len(&self, expected: usize) -> Result<(), ParseError>

Verify the tuple has the expected length.

Returns ParseErrorKind::UnexpectedTupleLength if length doesn’t match.

pub fn len(&self) -> usize

Get the total number of elements in the tuple.

pub fn is_empty(&self) -> bool

Check if the tuple is empty.

Trait Implementations

impl<'doc> Debug for TupleParser<'doc>

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

Formats the value using the given formatter.
