Here is the caller graph for this function:

equal() [2/2]

bool expect< void >::equal ( std::error_code const &  rhs ) const

Here is the call graph for this function:

error()

std::error_code expect< void >::error ( ) const

inlinenoexcept

Returns

Error - alway

Definition at line 375 of file expect.h.

{ return code_; }

has_error()

bool expect< void >::has_error ( ) const

inlinenoexcept

Returns

True if this is storing an error instead of a value.

Definition at line 372 of file expect.h.

{ return bool(code_); }

matches()

bool expect< void >::matches ( std::error_condition const &  rhs ) const

inlinenoexcept

Returns

False if has_value(), otherwise error() == rhs.

    }

Here is the call graph for this function:

operator bool()

expect< void >::operator bool ( ) const

inlineexplicitnoexcept

Returns

True if this is storing a value instead of an error.
