Struct Duplicates 

#[non_exhaustive]
pub struct Duplicates {
    pub key: String,
    pub on_match: OnMatch,
}

What a row does when a record already carries its key.

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.

key: String

The matched field whose value identifies a record.

on_match: OnMatch

Implementations

impl Duplicates

pub fn skip(key: impl Into<String>) -> Self

A row whose key is already there is passed over and noted.

pub fn update(key: impl Into<String>) -> Self

A row whose key is already there updates that record: the file’s columns over the record as it stands.
