Expand description
A count is used for the precision and width parameters of an integer, and can reference either an argument or a literal integer.
Variants§
CountIs(usize)
The count is specified explicitly.
CountIsName(&'a str, InnerSpan)
The count is specified by the argument with the given name.
CountIsParam(usize)
The count is specified by the argument at the given index.
CountIsStar(usize)
The count is specified by a star (like in {:.*}
) that refers to the argument at the given index.
CountImplied
The count is implied and cannot be explicitly specified.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
