Feature processing trait

Provided Methods§

source

fn dataset_begin(&mut self, name: Option<&str>) -> Result<()>

Begin of dataset processing

§Invariants

dataset_begin is called only once for an entire dataset.
dataset_begin is called before all other methods, including feature_begin, properties_begin, geometry_begin, and all methods from GeomProcessor and PropertyProcessor

source

fn dataset_end(&mut self) -> Result<()>

End of dataset processing

§Invariants

dataset_end is called only once for an entire dataset.
No other methods may be called after dataset_end.

source

fn feature_begin(&mut self, idx: u64) -> Result<()>

Begin of feature processing

idx: the positional row index in the dataset. For the nth row, idx will be n.
feature_begin will be called before both properties_begin and geometry_begin.

source

fn feature_end(&mut self, idx: u64) -> Result<()>

End of feature processing

idx: the positional row index in the dataset. For the nth row, idx will be n.
feature_end will be called after both properties_end and geometry_end.
