Expand description
Read trait
This is similar to BufRead
of standard library,
but can define its own error types, and can get a
reference with a long enough lifetime to implement zero-copy decode.
Associated Types
Required methods
Returns the available bytes.
The want value is the expected value. If the length of bytes returned is less than this value, zero-copy decoding will not be possible.
Returning empty bytes means EOF.
Provided methods
Step count
This method maybe called when the decode is started to calculate the decode depth. If it returns false, the decode will return a depth limit error.
