Struct PvdDecoder 

pub struct PvdDecoder { /* private fields */ }

PVD Decoder state

Implementations

impl PvdDecoder

pub fn decode_monitor_update( &self, data: &[u8], desc: &StructureDesc, ) -> DecodeResult<MonitorUpdate>

Decode a MONITOR update in specification order: changed bitset, then the delta data, then the overrun bitset.

pub fn decode_monitor_update_lenient( &self, data: &[u8], desc: &StructureDesc, ) -> DecodeResult<(MonitorUpdate, MonitorLayout)>

Try all three known layouts and report which one won.

For mid-stream packet captures, where the introspection was missed and the peer’s layout is unknown. Live connections should use PvdDecoder::decode_monitor_update.

impl PvdDecoder

pub fn new(is_be: bool) -> Self

pub fn with_limits(is_be: bool, limits: DecodeLimits) -> Self

Build a decoder with non-default array-length ceilings.

pub fn limits(&self) -> &DecodeLimits

The array-length ceilings this decoder was built with.

pub fn decode_size(&self, data: &[u8]) -> DecodeResult<(usize, usize)>

Decode a size value (PVA variable-length encoding)

pub fn decode_string(&self, data: &[u8]) -> DecodeResult<(String, usize)>

Decode a string

pub fn parse_field_desc(&self, data: &[u8]) -> DecodeResult<(FieldDesc, usize)>

Parse field description from introspection data

pub fn parse_introspection(&self, data: &[u8]) -> DecodeResult<StructureDesc>

Parse the full type introspection from INIT response

pub fn parse_introspection_with_len( &self, data: &[u8], ) -> DecodeResult<(StructureDesc, usize)>

Parse full type introspection and return consumed bytes.

pub fn decode_value( &self, data: &[u8], field_type: &FieldType, ) -> DecodeResult<(DecodedValue, usize)>

Decode value according to field type

pub fn decode_structure( &self, data: &[u8], desc: &StructureDesc, ) -> DecodeResult<(DecodedValue, usize)>

Decode a structure value using the field descriptions

pub fn decode_structure_with_bitset( &self, data: &[u8], desc: &StructureDesc, ) -> DecodeResult<(DecodedValue, usize)>

Decode a structure with a bitset indicating which fields are present This is used for delta updates in MONITOR
