Module const_panic::fmt

Formatting-related items

Panic formatting for custom types can be done in these ways (in increasing order of verbosity):

• Using the PanicFmt derive macro (requires the opt-in "derive" feature)
• Using the impl_panicfmt macro (requires the default-enabled "non_basic" feature)
• Using the flatten_panicvals macro (requires the default-enabled "non_basic" feature)
• Manually implementing the PanicFmt trait as described in its docs.

Structs

• ComputePvCountnon_basic
  For computing the PanicFmt::PV_COUNT of a struct or enum variant, with the call method.
• FmtArg
  Carries all of the configuration for formatting functions.
• IsCustomType
  Marker type used as the PanicFmt::Kind for user-defined types.
• IsPanicFmt
  A marker type that proves that S implements PanicFmt<This = T, Kind = K>.
• IsStdType
  Marker type used as the PanicFmt::Kind associated type for std types.
• PackedFmtArgnon_basic
  A version of FmtArg which occupies less space, but needs to be unpacked to be used.
• Separatornon_basic
  For alternate flag-aware separation of fields, collection elements, etc.

Enums

• Delimiternon_basic
  For outputting an alternate flag-aware delimiter.
• FmtKind
  What kind of formatting to do, either Display or Debug.
• IsLastnon_basic
  For telling Separator whether it comes after the last field or not.
• NumberFmt
  What integers are formatted as.
• TypeDelimnon_basic

Constants

  An alternate-flag-aware comma separator for use between fields or elements.
• COMMA_TERMnon_basic
  An alternate-flag-aware comma for use after the last field or element.
• INDENTATION_STEPnon_basic
  How much indentation (in spaces) is added with FmtArg::indent, and removed with FmtArg::unindent.
• SHORT_STRING_CAPnon_basic
  The capacity of a ShortString.

Traits
