Struct NameOpts

#[non_exhaustive]
pub struct NameOpts {
    pub recurse_ttl: isize,
}

Options for formatting the name of a type

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

recurse_ttl: isize

as long as this is > 0, keep formatting the type parameters when it reaches 0, format type parameters as ... if negative, all type parameters are formatted

Implementations

impl NameOpts

pub fn none() -> Self

Create a new NameOpts for which none of the type parameters are formatted

pub fn one() -> Self

Create a new NameOpts for which only the direct children are formatted

pub fn for_children(&self) -> Option<Self>

Decrease the recurse_ttl — if it’s != 0, returns options to pass when formatting children type parameters.

If this returns None and you have type parameters, you should render a … (unicode ellipsis) character instead of your list of types.

See the implementation for Vec for examples.
