Trait WithinRepeatLevel 

pub trait WithinRepeatLevel<'w>: 'w {
    // Required methods
    fn level_display_name() -> &'static str;
    fn current(ctx: &'w Context<'_>) -> Option<&'w Self>;
    fn for_each<'c, F, E>(ctx: &'c Context<'c>, call: F) -> Result<(), E>
       where F: FnMut(&Context<'_>, &Self) -> Result<(), E>,
             'c: 'w;

    // Provided method
    fn missing_repeat_level_special_error(
        _ctx: &'w Context<'_>,
        _span: Span,
    ) -> Option<Error> { ... }
}

Implemented for WithinVariant and WithinField

For combining code that applies similarly for different repeat levels.

Required Methods

fn level_display_name() -> &'static str

fn current(ctx: &'w Context<'_>) -> Option<&'w Self>

fn for_each<'c, F, E>(ctx: &'c Context<'c>, call: F) -> Result<(), E>

where F: FnMut(&Context<'_>, &Self) -> Result<(), E>, 'c: 'w,

Iterate over all the things at this level

If it needs a current container of the next level up (eg, a field needing a variant) and there is none current, iterates over containing things too.

Provided Methods

fn missing_repeat_level_special_error( _ctx: &'w Context<'_>, _span: Span, ) -> Option<Error>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
