Trait pointcloud::LabelSet[−][src]

pub trait LabelSet: Debug + Send + Sync + 'static {
    type Label: ?Sized + Serialize;
    type LabelSummary: Summary<Label = Self::Label>;
    fn len(&self) -> usize;
    fn is_empty(&self) -> bool;
    fn label(&self, pn: usize) -> PointCloudResult<Option<&Self::Label>>;
    fn label_summary(
        &self, 
        pns: &[usize]
    ) -> PointCloudResult<SummaryCounter<Self::LabelSummary>>;
}

A trait for a container that just holds labels. Meant to be used in conjunction with SimpleLabeledCloud to be and easy label or metadata object.

Associated Types

`type Label: ?Sized + Serialize`[src]

Underlying type.

`type LabelSummary: Summary<Label = Self::Label>`[src]

Summary of a set of labels

Required methods

`fn len(&self) -> usize`[src]

Number of elements in this label set

`fn is_empty(&self) -> bool`[src]

If there are no elements left in this label set

`fn label(&self, pn: usize) -> PointCloudResult<Option<&Self::Label>>`[src]

Grabs a label reference. Supports errors (the label could be remote), and partially labeled datasets with the option.

`fn label_summary( &self, pns: &[usize] ) -> PointCloudResult<SummaryCounter<Self::LabelSummary>>`[src]

Grabs a label summary of a set of indexes.
