Converts a stream of bytes into Thrift identifiers, primitives, containers, or structs.

This trait does not deal with higher-level Thrift concepts like structs or exceptions - only with primitives and message or container boundaries. Once bytes are read they are deserialized and an identifier (for example TMessageIdentifier) or a primitive is returned.

All methods return a thrift::Result. If an Err is returned the protocol instance and its underlying transport should be terminated.

Required Methods

fn read_message_begin(&mut self) -> Result<TMessageIdentifier>

Read the beginning of a Thrift message.

fn read_message_end(&mut self) -> Result<()>

Read the end of a Thrift message.

fn read_struct_begin(&mut self) -> Result<Option<TStructIdentifier>>

Read the beginning of a Thrift struct.

fn read_struct_end(&mut self) -> Result<()>

Read the end of a Thrift struct.

fn read_field_begin(&mut self) -> Result<TFieldIdentifier>

Read the beginning of a Thrift struct field.

fn read_field_end(&mut self) -> Result<()>

Read the end of a Thrift struct field.

fn read_bool(&mut self) -> Result<bool>

Read a bool.

fn read_bytes(&mut self) -> Result<Vec<u8>>

Read a fixed-length byte array.

fn read_i8(&mut self) -> Result<i8>

Read a word.

fn read_i16(&mut self) -> Result<i16>

Read a 16-bit signed integer.

fn read_i32(&mut self) -> Result<i32>

Read a 32-bit signed integer.

fn read_i64(&mut self) -> Result<i64>

Read a 64-bit signed integer.

fn read_double(&mut self) -> Result<f64>

Read a 64-bit float.

fn read_string(&mut self) -> Result<String>

fn read_list_begin(&mut self) -> Result<TListIdentifier>

Read the beginning of a list.

fn read_list_end(&mut self) -> Result<()>

fn read_map_begin(&mut self) -> Result<TMapIdentifier>

Read the beginning of a map.

fn read_map_end(&mut self) -> Result<()>

fn read_byte(&mut self) -> Result<u8>

Read an unsigned byte.

This method should never be used in generated code.

Provided Methods

fn skip(&mut self, field_type: TType) -> Result<()>

Skip a field with type field_type recursively until the default maximum skip depth is reached.

fn skip_till_depth(&mut self, field_type: TType, depth: i8) -> Result<()>
