Struct syndicate::value::reader::IOBinarySource

pub struct IOBinarySource<R>
where
    R: Read + Seek,
{
    pub read: R,
    /* private fields */
}

Implementation of BinarySource backed by an io::Read+io::Seek implementation.

Fields

read: R

The underlying byte source.

Implementations

impl<R> IOBinarySource<R>

where R: Read + Seek,

pub fn new(read: R) -> IOBinarySource<R>

Constructs an IOBinarySource from the given io::Read+io::Seek implementation.

Trait Implementations

impl<'de, R> BinarySource<'de> for IOBinarySource<R>

where R: Read + Seek,

type Mark = u64

Allows structured backtracking to an earlier position in an input.

fn mark( &mut self ) -> Result<<IOBinarySource<R> as BinarySource<'de>>::Mark, Error>

Retrieve a marker for the current position in the input.

fn restore( &mut self, mark: &<IOBinarySource<R> as BinarySource<'de>>::Mark ) -> Result<(), Error>

Seek the input to a previously-saved position.

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

Skip the next byte.

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

Returns the next byte without advancing over it.

fn readbytes(&mut self, count: usize) -> Result<Cow<'de, [u8]>, Error>

Returns and consumes the next count bytes, which must all be available. Always yields exactly count bytes or an error.

fn readbytes_into(&mut self, bs: &mut [u8]) -> Result<(), Error>

As BinarySource::readbytes, but uses bs as destination for the read bytes as well as taking the size of bs as the count of bytes to read.

fn packed<N, Dec>( &mut self, decode_embedded: Dec ) -> PackedReader<'de, '_, N, Dec, Self>

where N: NestedValue, Dec: DomainDecode<<N as NestedValue>::Embedded>,

Constructs a PackedReader that will read from self.

fn packed_iovalues( &mut self ) -> PackedReader<'de, '_, IOValue, IOValueDomainCodec, Self>

Constructs a PackedReader that will read IOValues from self.

fn text<N, Dec>( &mut self, decode_embedded: Dec ) -> TextReader<'de, '_, N, Dec, Self>

where N: NestedValue, Dec: DomainParse<<N as NestedValue>::Embedded>,

Constructs a TextReader that will read from self.

fn text_iovalues( &mut self ) -> TextReader<'de, '_, IOValue, ViaCodec<IOValueDomainCodec>, Self>

Constructs a TextReader that will read IOValues from self.
