Trait RecordsContext 

pub trait RecordsContext: Sized + Clone {
    // Provided method
    fn clone_for_iter(&self) -> Self { ... }
}

The context kept while performing records parsing.

Types which implement RecordsContext can be used as the long-lived context which is kept during records parsing. This context allows parsers to keep running computations over the span of multiple records.

Provided Methods

fn clone_for_iter(&self) -> Self

Clones a context for iterator purposes.

clone_for_iter is useful for cloning a context to be used by RecordsIter. Since Records::parse_with_context will do a full pass over all the records to check for errors, a RecordsIter should never error. Therefore, instead of doing checks when iterating (if a context was used for checks), a clone of a context can be made specifically for iterator purposes that does not do checks (which may be expensive).

The default implementation of this method is equivalent to Clone::clone.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
