◆ FlagsByte()

uint8_t Conversion::FlagsByte ( ) const

inlinenodiscardconstexpr

将前端解析出的标志位打包成共享的 FormatFlag 字节 / Pack the parsed frontend flags into the shared FormatFlag byte

Returns: 返回打包后的共享 FormatFlag 字节 / Returns the packed shared FormatFlag byte

Definition at line 52 of file printf_frontend_spec.hpp.

  {
    uint8_t flags = 0;
    if (left_align)
    {
      flags |= static_cast<uint8_t>(FormatFlag::LeftAlign);
    }
    if (force_sign)
    {
      flags |= static_cast<uint8_t>(FormatFlag::ForceSign);
    }
    if (space_sign)
    {
      flags |= static_cast<uint8_t>(FormatFlag::SpaceSign);
    }
    if (alternate)
    {
      flags |= static_cast<uint8_t>(FormatFlag::Alternate);
    }
    if (zero_pad)
    {
      flags |= static_cast<uint8_t>(FormatFlag::ZeroPad);
    }
    if (upper_case)
    {
      flags |= static_cast<uint8_t>(FormatFlag::UpperCase);
    }
    return flags;
  }

◆ PrecisionByte()

uint8_t Conversion::PrecisionByte ( ) const

inlinenodiscardconstexpr

返回共享精度字节；若未显式指定精度则为 0xFF / Return the shared precision byte, or 0xFF when precision is absent

Returns: 返回运行期协议期望的共享精度字节 / Returns the shared precision byte expected by the runtime protocol

Definition at line 86 of file printf_frontend_spec.hpp.

  {
    return has_precision ? precision : std::numeric_limits<uint8_t>::max();
  }
