Detailed Description

Abstract base class for deserialization data sources.

Member Function Documentation

virtual void eagine::deserializer_data_source::pop ( span_size_t size )

pure virtual

Returns the specified amount of data of the top of the source.

auto eagine::deserializer_data_source::scan_for	(	byte	what,
		const valid_if_positive< span_size_t > &	max,
		const valid_if_positive< span_size_t > &	step = `{256}`
	)		-> valid_if_nonnegative<span_size_t>

inline

Returns the position of the first occurrence of the specified byte.

Parameters

what	the searched value.
max	the maximum number of bytes from the top to scan.
step	how much data should be fetched per scan iteration.

template<typename Function >

auto eagine::deserializer_data_source::scan_until	(	Function	predicate,
		const valid_if_positive< span_size_t > &	max,
		const valid_if_positive< span_size_t > &	step = `{256}`
	)		-> valid_if_nonnegative<span_size_t>

inline

Returns the position of the first byte where predicate is true.

Parameters

predicate	the function indicating where to stop the scan.
max	the maximum number of bytes from the top to scan.
step	how much data should be fetched per scan iteration.

virtual auto eagine::deserializer_data_source::top ( span_size_t size ) -> memory::const_block

pure virtual

Returns a block covering the specified amount of data of the top.
