Trait flow_arena::prelude::FlowMap

pub trait FlowMap: FlowBase + FlowCheck {
    fn grow(&mut self, obj: Self::Node) -> Result<Self::Id, FlowError>;
    fn erase(&mut self, obj: &Self::Id) -> Result<Self::Node, FlowError>;
}

provides hashmap functionality

Required methods

fn grow(&mut self, obj: Self::Node) -> Result<Self::Id, FlowError>

inserts a node; returns err if id exists.

fn erase(&mut self, obj: &Self::Id) -> Result<Self::Node, FlowError>

removes a node; returns err if id not found under root
