Member Function Documentation

SourceData()

template<Text Source>

static constexpr const char * LibXR::Print::Printf::Compiler< Source >::SourceData ( )

inlinestaticnodiscardconstexpr

返回去掉结尾零字节后的源字符串数据 / Return the underlying source bytes without the terminating zero byte

Returns

指向当前格式字面量正文的指针 / Returns a pointer to the literal body

Definition at line 92 of file printf_frontend_detail.hpp.

{ return Source.Data(); }

SourceSize()

template<Text Source>

static constexpr size_t LibXR::Print::Printf::Compiler< Source >::SourceSize ( )

inlinestaticnodiscardconstexpr

返回去掉结尾零字节后的源字符串长度 / Return the source length without the terminating zero byte

Returns

当前格式字面量正文长度 / Returns the literal-body size

Definition at line 98 of file printf_frontend_detail.hpp.

{ return Source.Size(); }

Walk()

template<Text Source>

static consteval ErrorType LibXR::Print::Printf::Compiler< Source >::Walk ( auto & visitor )

inlinestaticnodiscardconsteval

按源串顺序遍历这条字面量，并产出文本片段和最终字段记录 / Walk the literal in source order and emit text spans plus final field records

Parameters

visitor

接收文本片段与最终字段记录的 visitor / Visitor receiving text spans and final field records

Returns

首个源级解析错误或字段选择错误；成功时返回 Error::None / Returns the first source-level parse or field-selection error; returns Error::None on success

Definition at line 108 of file printf_frontend_detail.hpp.

  {
    return Detail::PrintfCompile::WalkSourceAsFormatFields<Source>(visitor);
  }
