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.

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

operator<<

Streams a safe_int's wrapped value to an output stream

operator==

Equality operators

operator<=>

Three‐way comparison operators

Name

Description

unspecified

The default value of a customization point that has not yet been specialized.

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).
