Class List

Here are the classes, structs, unions and interfaces with brief descriptions:

Nfe
Nlct
CNode	This is an intrusive Link-Cut-Tree
Nsys
CCmdNotFound	Thrown by sys::require_cmd when a command cannot be located on the system
Nterm	Lightweight stream-based terminal colors for diagnostics and CLI output
CCited	An owning message fragment that spells `citations` of its own; what format_cite yields
CCite	A borrowed fragment whose backticks stay markup; format_cite escapes every other argument
Nutf8	UTF-8 helpers for decoding byte streams, encoding char32_t values, and running ASCII-style character classification on char32_t
CChar32	Wrapper for char32_t with an operator<< that writes UTF-8
CArena	An arena pre-allocates so-called pages of size Arena::page_size_
CMemoryResource	A memory resource bridge in order to use this Arena for pmr containers
CAllocator	An allocator in order to use this Arena for containers
CDeleter
CRef	A non-owning pointer into an Arena
Cbasic_ostream_formatter	Make types that support ostream operators available for std::format
CBitset	A dynamically growing set of bits with small storage optimization
Creference	Proxy that Bitset::operator[] hands out to read/write the bit it refers to
Citerator	Iterates over the indices of all set bits in ascending order
CHash
CCite	A borrowed fragment whose backticks stay markup; format_cite escapes every other argument
CCited	An owning message fragment that spells `citations` of its own; what format_cite yields
CCli	A small command-line parser for a single command - no subcommands
CCodeDiag	The Diag a Driver installs by default: colors a `citation` and drops its backticks - or keeps them verbatim without color; \` is a literal backtick and \\ a literal backslash
CDbg	The debug info of an entity: where it came from and what it was called
CHash
CEq
CDbgKey	Opaque handle to a Dbg interned in a Driver; see Driver::dbg
CDiag	How a diagnostic lays out - and how much of it an Error keeps
CDriver	Use/derive from this class for "global" variables that you need all over the place
CError	Collects diagnostics and hands each to the Diag that lays it out
CBail	What Error::ack and Error::bail throw
CNote	A secondary message elaborating a Msg
CMsg	One Tag::Error or Tag::Warn together with the Notes that belong to it
Cis_bit_enum
CJoin	Join elements of range with sep
CLexer	The blueprint for a lexer with a buffer of K tokens to peek into the future (Lexer::ahead)
CAhead	A decoded code point together with the byte range it occupies
CLoc	Location within a Src: the half-open byte range [Loc::begin, Loc::end)
CLog	Facility to log what you are doing
CFmtLoc	A cite_string that remembers where it was written
CParser	The blueprint for a recursive descent/ ascent parser using a K lookahead of Tokens
CTracker
CAnchor	RAII helper that anchors a Tag for its lifetime; use Parser::anchor to build one
CPathHash	Hashes a std::filesystem::path - consistent with its operator==, which compares lexically
CPatricia	Hash-consed, immutable sets of D*, ordered by an unsigned id the elements carry themselves
CSet	An immutable set - really just a tagged pointer, so copy it around freely
Citerator	Yields the D* in ascending Key::key order
CPos	Byte offset into a Src; pass around as value
CProfiler	Records wall-clock timings for (possibly nested) named Profiler::Spans and reports them in various formats
CSpan	A single run
CRestore	RAII guard that restores a value at the end of the scope
CRestore< T, nullptr, nullptr >	Restores ref to its current value at the end of the scope
CRing	A ring buffer with N elements
CRing< T, 1 >	Specialization if N == 1 - doesn't need a ring
CRing< T, 2 >	Specialization if N == 2; doesn't need a ring, we just copy
CRuntimeCast	Inherit from this class using CRTP, for some nice dynamic_cast-style wrappers
CSnippet	The underlined source excerpt that goes below a diagnostic
CSpan	This is a thin wrapper for std::span<T, N> with the following additional features:
CSrc	The content of one source file together with the offsets its rows start at
CSrcMap	Interns the text - and the std::filesystem::path - of every file a Loc may point into
CStreamFn	Wrap a callable f(std::ostream&) -> std::ostream& so it streams via operator<< and std::format
CSym	A Symbol just wraps a pointer to Sym::String, so pass Sym itself around as value
CString
CEqual
CHash	Hashes the characters, not the pointer - String::Equal compares them, and the two have to agree
CHash
CEq
CSymPool	Hash set where all strings - wrapped in Symbol - live in
CSymTab	A fixed-capacity Symbol -> V map for a closed set of Size entries: filled once, then only looked up - a Lexer's reserved words, say
CTab	Keeps track of indentation level during output
CVector	This is a thin wrapper for absl::InlinedVector<T, N, A> which is a drop-in replacement for std::vector<T, A>
CVLA	CRTP base that gives Self one VLA per element type in Self::VLA_Types directly behind it in memory - the C flexible array member, generalized to several arrays of different type
CWorklist	A worklist that pushes each element at most once
CXTrie	Hash-consed sets of D*
CSet
Citerator
Nstd
Ctuple_size< fe::Span< T, N > >
Ctuple_element< I, fe::Span< T, N > >
