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.
