Trait pointcloud::LabelSet

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

Underlying type.

type LabelSummary: Summary<Label = Self::Label>

Summary of a set of labels

Required methods

pub fn len(&self) -> usize

Number of elements in this label set

pub fn is_empty(&self) -> bool

If there are no elements left in this label set

pub fn label(&self, pn: usize) -> PointCloudResult<Option<&Self::Label>>

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

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

Grabs a label summary of a set of indexes.
