Extension trait for text encodings.

Required Methods

fn encode_record_with_sym<R: DbnEncodable>( &mut self, record: &R, symbol: Option<&str>, ) -> Result<()>

Encodes a single DBN record of type R along with the record’s text symbol.

Errors

This function returns an error if it’s unable to write to the underlying writer or there’s a serialization error.

Provided Methods

fn encode_ref_with_sym( &mut self, record: RecordRef<'_>, symbol: Option<&str>, ) -> Result<()>

Encodes a single DBN RecordRef along with the record’s text symbol.

Errors

This function returns an error if it’s unable to write to the underlying writer or there’s a serialization error.

unsafe fn encode_ref_ts_out_with_sym( &mut self, record: RecordRef<'_>, ts_out: bool, symbol: Option<&str>, ) -> Result<()>

Encodes a single DBN RecordRef with an optional ts_out (see record::WithTsOut) along with the record’s text symbol.

Safety

ts_out must be false if record does not have an appended ts_out.

Errors

This function returns an error if it’s unable to write to the underlying writer or there’s a serialization error.

Object Safety

This trait is not object safe.
