ram_table() [1/4]

template<typename Builder >

proof_system::plonk::stdlib::ram_table< Builder >::ram_table	(	Builder *	builder,
		const size_t	table_size
	)

Construct a new ram table<Builder>::ram table object. It's dynamic memory!

Template Parameters

Member Function Documentation

initialize_table()

template<typename Builder >

void proof_system::plonk::stdlib::ram_table< Builder >::initialize_table

internal method, is used to call Builder methods that will generate RAM table.

initialize the table once we perform a read. This ensures we always have a pointer to a Builder. (if both the table entries and the index are constant, we don't need a builder as we can directly extract the desired value fram _raw_entries)

Template Parameters

Builder

operator=() [1/2]

template<typename Builder >

ram_table< Builder > & proof_system::plonk::stdlib::ram_table< Builder >::operator=

(

const ram_table< Builder > &

other

)

Copy assignment operator.

Template Parameters

Builder

Parameters

other

Returns

ram_table<Builder>&

operator=() [2/2]

template<typename Builder >

ram_table< Builder > & proof_system::plonk::stdlib::ram_table< Builder >::operator=

(

ram_table< Builder > &&

other

)

Move assignment operator.

Template Parameters

Builder

Parameters

other

Returns

ram_table<Builder>&

read()

template<typename Builder >

field_t< Builder > proof_system::plonk::stdlib::ram_table< Builder >::read

(

const field_pt &

index

)

const

Read a field element from the RAM table at an index value.

Template Parameters

Builder

Parameters

index

Returns

field_t<Builder>

write()

template<typename Builder >

void proof_system::plonk::stdlib::ram_table< Builder >::write	(	const field_pt &	index,
		const field_pt &	value
	)

Write a field element from the RAM table at an index value.

Template Parameters

Builder

Parameters

index
value
