Struct ComponentDescriptor 

pub struct ComponentDescriptor {
    pub archetype: Option<ArchetypeName>,
    pub component: ComponentIdentifier,
    pub component_type: Option<ComponentType>,
}

A ComponentDescriptor fully describes the semantics of a column of data.

Every component at a given entity path is uniquely identified by the component field of the descriptor. The archetype and component_type fields provide additional information about the semantics of the data.

Fields

archetype: Option<ArchetypeName>

Optional name of the Archetype associated with this data.

None if the data wasn’t logged through an archetype.

Example: rerun.archetypes.Points3D.

component: ComponentIdentifier

Uniquely identifies of the component associated with this data.

Example: Points3D:positions.

component_type: Option<ComponentType>

Optional type information for this component.

Can be used to inform applications on how to interpret the data.

Example: rerun.components.Position3D.

Implementations

impl ComponentDescriptor

pub fn sanity_check(&self)

pub fn display_name(&self) -> &str

Short and usually unique, used in UI.

impl ComponentDescriptor

pub fn partial(component: impl Into<ComponentIdentifier>) -> ComponentDescriptor

Creates a new component descriptor that only has the component set.

Both archetype and component_type will be missing.

pub fn with_archetype( self, archetype_name: ArchetypeName, ) -> ComponentDescriptor

Unconditionally sets Self::archetype to the given one.

pub fn with_component_type( self, component_type: ComponentType, ) -> ComponentDescriptor

Unconditionally sets Self::component to the given one.

pub fn or_with_archetype( self, archetype_name: impl Fn() -> ArchetypeName, ) -> ComponentDescriptor

Sets Self::archetype to the given one iff it’s not already set.

pub fn or_with_component_type( self, component_type: impl FnOnce() -> ComponentType, ) -> ComponentDescriptor

Sets Self::component_type to the given one iff it’s not already set.
