Trait defining layer operations

Required Associated Types

type LayeredViewType

Required Methods

fn layers<L: Into<Layer>>( &self, names: L, ) -> Result<Self::LayeredViewType, GraphError>

Return a graph containing the layers in names. Errors if one or more of the layers do not exists.

fn exclude_layers<L: Into<Layer>>( &self, layers: L, ) -> Result<Self::LayeredViewType, GraphError>

Return a graph containing the excluded layers in names. Errors if one or more of the layers do not exists.

fn exclude_valid_layers<L: Into<Layer>>( &self, layers: L, ) -> Self::LayeredViewType

fn has_layer(&self, name: &str) -> bool

Check if name is a valid layer name

fn valid_layers<L: Into<Layer>>(&self, names: L) -> Self::LayeredViewType

Return a graph containing the layers in names. Any layers that do not exist are ignored.

Provided Methods

fn default_layer(&self) -> Self::LayeredViewType

Return a graph containing only the default edge layer
