Types

Name	Description
`constrained`	A transparent wrapper that carries an error policy for domain constraint enforcement.
`fill_align_width_format_specs`	The fill/align/width part of a `std-format-spec`, as parsed by `parse_fill_align_width`.
`fill_t`	The fill character(s) of a `std-format-spec`, storing at most one Unicode code point.
`fmt_arg_ref`	A reference to a format argument, by index or (when using fmtlib) by name.
`safe_int`	Wraps an integral type with overflow detection.
`safe_int_terminate_policy`	Error policy that terminates the program on overflow (always available, freestanding-safe).
`safe_int_throw_policy`	Error policy that throws std::overflow_error on overflow (hosted only).
`terminate_policy`	Error policy that terminates the program on constraint violation (freestanding-safe).
`throw_policy`	Error policy that throws std::domain_error on constraint violation (hosted only).
`unspecified_t`	Sentinel type for a specializable variable-template customization point with no usable default.
`width_checker`	A `Handler` for `handle_dynamic_spec` that validates and extracts a `width` argument.

Functions

Name	Description
`at_most_one_of`	Finds the single modifier from `modifiers` present in [begin, end).]
`handle_dynamic_spec`	Resolves a dynamic (`{}`-style) spec against the format arguments.
`operator%`	Modulus operators
`operator*`	Multiplication operators
`operator+`	Unary plus operators
`operator-`	Unary minus operators
`operator/`	Division operators
`parse_align`	Parses the fill and alignment part of a `std-format-spec` into `specs.`
`parse_dynamic_spec`	Parses a spec value that may be a literal integer or a `{}`-style dynamic argument reference.
`parse_fill_align_width`	Parses the fill/align/width part of a `std-format-spec` into `specs.`
`parse_nonnegative_int`	Parses the range [begin, end) as an unsigned integer.]
`write_padded`	Writes a string to an output iterator with fill/align/width padding.
`operator<<`	Streams a safe_int's wrapped value to an output stream
`operator==`	Equality operators
`operator<=>`	Three-way comparison operators

Variables

Name	Description
`unspecified`	The default value of a customization point that has not yet been specialized.

Concepts

Name	Description
`Complex`	A complex-field representation type.
`ComplexScalar`	A complex scalar: complex field with `real()`/`imag()`/`modulus()`.
`ConstraintPolicy`	Concept satisfied by error policy types usable with `constrained`.
`OverflowPolicy`	Concept satisfied by overflow error policies usable with `safe_int`.
`Real`	A real-field representation type.
`RealScalar`	A real scalar (tensor order 0): real field, totally ordered, self-scalable.
`Scalar`	A scalar (real or complex, tensor order 0) - the element type a vector/tensor is built from.
`Tensor`	A second-order tensor (or a lower-order type filling its slot).
`Vector`	A vector (a scalar, or a magnitude-bearing tensor-order-1 type).
`specified`	Satisfied when a customization point has been given a value (i.e. is not `unspecified`).
