Module encoding

Expand description

Contains the BinaryEncodable trait and helpers for reading and writing of scalar values and other primitives.

Macros§

impl_encoded_as: Implement the encodable traits for a type, using the provided functions to convert to and from some other type.

DecodingOptions: General decoding options.
DepthGauge: Depth gauge is used on potentially recursive structures like Variant & ExtensionObject during decoding to limit the depth the decoder will go before giving up.
DepthLock: Depth lock holds a reference on the depth gauge. The drop ensures impl that the reference is decremented even if there is a panic unwind.
Error: General OPC-UA error.

BinaryDecodable: Trait for decoding a type from OPC UA binary.
BinaryEncodable: OPC UA Binary Encoding interface. Anything that encodes to binary must implement this. It provides functions to calculate the size in bytes of the struct (for allocating memory), encoding to a stream and decoding from a stream.
SimpleBinaryDecodable: Trait for decoding a type that cannot contain any custom types from OPC UA binary. Used in some core modules to decode raw binary messages.
SimpleBinaryEncodable: Trait for encoding a type that cannot contain any custom types to OPC UA binary. Used in some core modules to encode raw binary messages.
UaNullable: Trait implemented by OPC-UA types, indicating whether they are null or not, for use in encoding.

byte_len_array: Calculates the length in bytes of an array of encoded type
process_decode_io_result: Converts an IO encoding error (and logs when in error) into an EncodingResult
process_encode_io_result: Converts an IO encoding error (and logs when in error) into an EncodingResult
read_bytes: Reads an array of bytes from the stream
read_f32: Read a 32-bit precision value from the stream
read_f64: Read a 64-bit precision from the stream
read_i16: Read an signed 16-bit value from the stream
read_i32: Read a signed 32-bit value from the stream
read_i64: Read a signed 64-bit value from the stream
read_u8: Read an unsigned byte from the stream
read_u16: Read an unsigned 16-bit value from the stream
read_u32: Read an unsigned 32-bit value from the stream
