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.

Don’t accept numbered variants and fields.

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
