Struct ketree::treebuilder::TreeBuilder

pub struct TreeBuilder<'a> { /* fields omitted */ }

Contains the code to be executed as a prologue, body, and epilogue.

Methods

impl<'a> TreeBuilder<'a>

fn new(body: &'a str, pr: &'a str, ep: &'a str) -> TreeBuilder<'a>

Creates a new TreeBuilder with provided 'body' code.

fn set_body(&mut self, s: &'a str)

Sets the body of code to be executed.

fn set_prologue(&mut self, s: &'a str)

Sets the prologue to be executed.

fn set_epilogue(&mut self, s: &'a str)

Sets the epilogue to be executed.

fn use_box_and_name<T, B>(
    &self,
    cml: Box<B>,
    tree_name: &str
) -> Result<(Tree<T>, HashSet<String>), Error> where
    T: 'static + Clone + Debug,
    B: 'static + ModuleLoader, 

Consumes a Box containing a ketos::ModuleLoader and takes a name to look for that the tree is assigned to (using define in the body of Ketos code).

Returns a tuple containing the Tree and a HashSet of variable names.

fn use_box_set_and_name<T, B>(
    &self,
    cml: Box<B>,
    var_set: HashSet<String>,
    tree_name: &str
) -> Result<(Tree<T>, HashSet<String>), Error> where
    T: 'static + Clone + Debug,
    B: 'static + ModuleLoader, 

Consumes a Box containing a ketos::ModuleLoader, consumes a HashSet (to allow for the selection of the hashing algorithm), and takes a name to look for that the tree is assigned to (using define in the body of Ketos code).

Returns a tuple containing the Tree and the consumed HashSet filled with variable names.
