builders
num	Integer and floating-point number formatting
rt	[Unstable]

Arguments	This structure represents a safely precompiled version of a format string and its arguments. This cannot be generated at runtime because it cannot safely be done so, so no constructors are given and the fields are private to prevent modification.
DebugList	A struct to help with `fmt::Debug` implementations.
DebugMap	A struct to help with `fmt::Debug` implementations.
DebugSet	A struct to help with `fmt::Debug` implementations.
DebugStruct	A struct to help with `fmt::Debug` implementations.
DebugTuple	A struct to help with `fmt::Debug` implementations.
Error	The error type which is returned from formatting a message into a stream.
Formatter	A struct to represent both where to emit formatting strings to and how they should be formatted. A mutable version of this is passed to all formatting traits.
ArgumentV1	[Unstable] This struct represents the generic "argument" which is taken by the Xprintf family of functions. It contains a function to format the given value. At compile time it is ensured that the function and the value have the correct types, and then this struct is used to canonicalize arguments to one type.
Radix	[Deprecated] A radix with in the range of `2..36`.
RadixFmt	[Deprecated] A helper type for formatting radixes.

FlagV1
Void

Binary	Format trait for the `b` character.
Debug	Format trait for the `?` character.
Display	Format trait for an empty format, `{}`.
LowerExp	Format trait for the `e` character.
LowerHex	Format trait for the `x` character.
Octal	Format trait for the `o` character.
Pointer	Format trait for the `p` character.
UpperExp	Format trait for the `E` character.
UpperHex	Format trait for the `X` character.
Write	A collection of methods that are required to format a message into a stream.

float_to_decimal_common
float_to_exponential_common
write	The `write` function takes an output stream, a precompiled format string, and a list of arguments. The arguments will be formatted according to the specified format string into the output stream provided.
radix	[Deprecated] Constructs a radix formatter in the range of `2..36`.

The type returned by formatter methods.
