pub fn zcash_deserialize_string_external_count<R: Read>(
external_byte_count: usize,
reader: R,
) -> Result<String, SerializationError>
Expand description
zcash_deserialize_external_count
, specialised for String
.
The external count is in bytes. (Not UTF-8 characters.)
This allows us to optimize the inner loop into a single call to read_exact()
.
This function has a zcash_
prefix to alert the reader that the
serialization in use is consensus-critical serialization, rather than
some other kind of serialization.
