pub trait ItemArgument {
// Required method
fn write_arg_onto(&self, out: &mut ItemEncoder<'_>) -> Result<(), Bug>;
}Expand description
Types that can be added as argument(s) to item keyword lines
Implemented for strings, and various other types.
This is a separate trait so we can control the formatting of (eg) Iso8601TimeSp,
without having a method on ItemEncoder for each argument type.
Required Methods§
Sourcefn write_arg_onto(&self, out: &mut ItemEncoder<'_>) -> Result<(), Bug>
fn write_arg_onto(&self, out: &mut ItemEncoder<'_>) -> Result<(), Bug>
Format as a string suitable for including as a netdoc keyword line argument
The implementation is responsible for checking that the syntax is legal.
For example, if self is a string, it must check that the string is
in legal as a single argument.
Some netdoc values (eg times) turn into several arguments; in that case,
one ItemArgument may format into multiple arguments, and this method
is responsible for writing them all, with the necessary spaces.
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
