source§

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

source

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

source§

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

source

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.

source

source

pub fn disable_legacy_enums(self) -> Self

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

source

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.

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.

source§
