Struct TextReader 

pub struct TextReader<'de, 'src, N, Dec, S>
where
    N: NestedValue,
    Dec: DomainParse<<N as NestedValue>::Embedded>,
    S: BinarySource<'de>,
{
    pub source: &'src mut S,
    pub dec: Dec,
    pub toplevel_whitespace_mode: ToplevelWhitespaceMode,
    /* private fields */
}

The text syntax Preserves reader.

Fields

source: &'src mut S

Underlying source of (utf8) bytes.

dec: Dec

Decoder for producing Rust values embedded in the text.

toplevel_whitespace_mode: ToplevelWhitespaceMode

Treatment of whitespace before a toplevel term.

Implementations

impl<'de, 'src, N, Dec, S> TextReader<'de, 'src, N, Dec, S>

where N: NestedValue, Dec: DomainParse<<N as NestedValue>::Embedded>, S: BinarySource<'de>,

pub fn new(source: &'src mut S, dec: Dec) -> TextReader<'de, 'src, N, Dec, S>

Construct a new reader from a byte (utf8) source and embedded-value decoder.

pub fn toplevel_whitespace_mode( self, new_mode: ToplevelWhitespaceMode, ) -> TextReader<'de, 'src, N, Dec, S>

pub fn next_iovalue(&mut self, read_annotations: bool) -> Result<IOValue, Error>

Retrieve the next IOValue in the input stream.

Trait Implementations

impl<'de, 'src, N, Dec, S> Reader<'de, N> for TextReader<'de, 'src, N, Dec, S>

where N: NestedValue, Dec: DomainParse<<N as NestedValue>::Embedded>, S: BinarySource<'de>,

type Mark = <S as BinarySource<'de>>::Mark

Allows structured backtracking to an earlier stage in a parse. Useful for layering parser combinators atop a Reader.

fn next(&mut self, read_annotations: bool) -> Result<Option<N>, Error>

Retrieve the next parseable value or an indication of end-of-input.

fn mark( &mut self, ) -> Result<<TextReader<'de, 'src, N, Dec, S> as Reader<'de, N>>::Mark, Error>

Retrieve a marker for the current position in the input.

fn restore( &mut self, mark: &<TextReader<'de, 'src, N, Dec, S> as Reader<'de, N>>::Mark, ) -> Result<(), Error>

Seek the input to a previously-saved position.

fn next_token( &mut self, read_embedded_annotations: bool, ) -> Result<Token<N>, Error>

Get the next SAX-style event, discarding annotations.

fn next_annotations_and_token(&mut self) -> Result<(Vec<N>, Token<N>), Error>

Get the next SAX-style event, plus a vector containing any annotations that preceded it.

fn skip_value(&mut self) -> Result<(), Error>

Skips the next available complete value. Yields an error if no such value exists.

fn demand_next(&mut self, read_annotations: bool) -> Result<N, Error>

Retrieve the next parseable value, treating end-of-input as an error.

fn next_boolean(&mut self) -> Result<bool, Error>

Yields the next value, if it is a Boolean, or an error otherwise.

fn next_double(&mut self) -> Result<Double, Error>

Yields the next value, if it is a Double, or an error otherwise.

fn next_signedinteger(&mut self) -> Result<SignedInteger, Error>

Yields the next value, if it is a SignedInteger, or an error otherwise.

fn next_i8(&mut self) -> Result<i8, Error>

Yields the next value, if it is a SignedInteger that fits in i8, or an error otherwise.

fn next_u8(&mut self) -> Result<u8, Error>

fn next_i16(&mut self) -> Result<i16, Error>

Yields the next value, if it is a SignedInteger that fits in i16, or an error otherwise.

fn next_u16(&mut self) -> Result<u16, Error>

Yields the next value, if it is a SignedInteger that fits in u16, or an error otherwise.

fn next_i32(&mut self) -> Result<i32, Error>

Yields the next value, if it is a SignedInteger that fits in i32, or an error otherwise.

fn next_u32(&mut self) -> Result<u32, Error>

Yields the next value, if it is a SignedInteger that fits in u32, or an error otherwise.

fn next_i64(&mut self) -> Result<i64, Error>

fn next_u64(&mut self) -> Result<u64, Error>

Yields the next value, if it is a SignedInteger that fits in u64, or an error otherwise.

fn next_i128(&mut self) -> Result<i128, Error>

Yields the next value, if it is a SignedInteger that fits in i128, or an error otherwise.

fn next_u128(&mut self) -> Result<u128, Error>

Yields the next value, if it is a SignedInteger that fits in u128, or an error otherwise.

fn next_f64(&mut self) -> Result<f64, Error>

Yields the next value as an f64, if it is a Double, or an error otherwise.

fn next_char(&mut self) -> Result<char, Error>
