Implementations

impl<R> Deserializer<IoRead<R>>where
    R: Read,

pub fn from_reader(reader: R) -> Deserializer<IoRead<R>>

Constructs a Deserializer which reads from a Reader.

impl<'a> Deserializer<SliceRead<'a>>

pub fn from_slice(bytes: &'a [u8]) -> Deserializer<SliceRead<'a>>

Constructs a Deserializer which reads from a slice.

Borrowed strings and byte slices will be provided when possible.

impl<'a> Deserializer<MutSliceRead<'a>>

pub fn from_mut_slice(bytes: &'a mut [u8]) -> Deserializer<MutSliceRead<'a>>

Constructs a Deserializer which reads from a mutable slice that doubles as its own scratch buffer.

Borrowed strings and byte slices will be provided even for indefinite strings.

impl<'de, R> Deserializer<R>where
    R: Read<'de>,

pub fn new(read: R) -> Self

Constructs a Deserializer from one of the possible serde_cbor input sources.

from_slice and from_reader should normally be used instead of this method.

pub fn disable_named_format(self) -> Self

Don’t accept named variants and fields.

pub fn disable_packed_format(self) -> Self

Don’t accept numbered variants and fields.

pub fn disable_standard_enums(self) -> Self

Don’t accept the new enum format used by serde_cbor versions >= v0.10.

pub fn disable_legacy_enums(self) -> Self

Don’t accept the old enum format used by serde_cbor versions <= v0.9.

pub fn end(&mut self) -> Result<()>

This method should be called after a value has been deserialized to ensure there is no trailing data in the input source.

pub fn into_iter<T>(self) -> StreamDeserializer<'de, R, T> where
    T: Deserialize<'de>,

Turn a CBOR deserializer into an iterator over values of type T.

impl<R> Deserializer<R>where
    R: Offset,

pub fn byte_offset(&self) -> usize

Return the current offset in the reader
