Struct preserves::value::reader::IOBinarySource

pub struct IOBinarySource<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: Read + Seek> IOBinarySource<R>

pub fn new(read: R) -> Self

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

Trait Implementations

impl<'de, R: Read + Seek> BinarySource<'de> for IOBinarySource<R>

type Mark = u64

Allows structured backtracking to an earlier position in an input.

fn mark(&mut self) -> Result<Self::Mark>

Retrieve a marker for the current position in the input.

fn restore(&mut self, mark: &Self::Mark) -> Result<()>

Seek the input to a previously-saved position.

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

Skip the next byte.

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

Returns the next byte without advancing over it.

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

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<()>

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: NestedValue, Dec: DomainDecode<N::Embedded>>( &mut self, decode_embedded: Dec ) -> PackedReader<'de, '_, N, Dec, Self>

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: NestedValue, Dec: DomainParse<N::Embedded>>( &mut self, decode_embedded: Dec ) -> TextReader<'de, '_, N, Dec, Self>

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.
