Trait Value 

pub trait Value: Sealed {
    // Required method
    fn record(&self, key: &Field, visitor: &mut dyn Visit);
}

A field value of an erased type.

Implementors of Value may call the appropriate typed recording methods on the visitor passed to their record method in order to indicate how their data should be recorded.

Required Methods

fn record(&self, key: &Field, visitor: &mut dyn Visit)

Visits this value with the given Visitor.

Trait Implementations

impl Display for dyn Value

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>
