Struct FileSinkBuilder

pub struct FileSinkBuilder<ArgPath> { /* private fields */ }

Note

The generics here are designed to check for required fields at compile time, users should not specify them manually and/or depend on them. If the generic concrete types or the number of generic types are changed in the future, it may not be considered as a breaking change.
