Struct minicbor_io::Reader [−][src]
Wraps a std::io::Read
and reads length-delimited CBOR values.
Implementations
impl<R> Reader<R>
[src]
pub fn new(reader: R) -> Self
[src]
Create a new reader with a max. buffer size of 512KiB.
pub fn with_buffer(reader: R, buffer: Vec<u8>) -> Self
[src]
Create a new reader with a max. buffer size of 512KiB.
pub fn set_max_len(&mut self, val: u32)
[src]
Set the max. buffer size in bytes.
If length values greater than this are decoded, an
Error::InvalidLen
will be returned.
pub fn reader(&self) -> &R
[src]
Get a reference to the inner reader.
pub fn reader_mut(&mut self) -> &mut R
[src]
Get a mutable reference to the inner reader.
pub fn into_parts(self) -> (R, Vec<u8>)
[src]
Deconstruct this reader into the inner reader and the buffer.
impl<R: Read> Reader<R>
[src]
pub fn read<'a, T: Decode<'a>>(&'a mut self) -> Result<Option<T>, Error>
[src]
Read the next CBOR value and decode it.
The value is assumed to be preceded by a u32
(4 bytes in network
byte order) denoting the length of the CBOR item in bytes.
Reading 0 bytes when decoding the length prefix results in Ok(None)
,
otherwise either Some
value or an error is returned.
