std::philox_engine<UIntType,w,n,r,consts>::seed - cppreference.com

From cppreference.com

void seed( result_type value = default_seed );

(1) (since C++26)

template< class SeedSeq > void seed( SeedSeq& seq );

(2) (since C++26)

Sets the state of the random-number engine.

1) Right after the state is set, *this == std::philox_engine(value) is true.

2) Right after the state is set, *this == std::philox_engine(seq) is true.

Parameters

value - seed value to use to set the state
seq - seed sequence to use to set the state

Exceptions

2) If SeedSeq is not std::seed_seq, throws the exceptions thrown by the seq.generate call.

Complexity

1) Same as std::philox_engine(value).

2) Same as std::philox_engine(seq).
