Struct brane_ast::state::DataState

source ·
pub struct DataState { /* private fields */ }
Expand description

Defines a DataState, which is a bit like a symbol table for data identifiers - except that it’s temporal (i.e., has a notion of values being overwritten).

Implementations§

source§

impl DataState

source

pub fn new() -> Self

Constructor for the DataTable that initializes it to empty.

§Returns

A new DataTable instance.

source

pub fn set_funcs(&mut self, name: impl Into<String>, new_ids: HashSet<Data>)

Sets a whole list of new possible values for this function, overwriting any existing ones.

§Arguments
  • name: The name of the function to set the possible datasets for.
  • new_ids: The Data/IntermediateResult identifier to add as possible return dataset for this function.
source

pub fn set_vars(&mut self, name: impl Into<String>, new_ids: HashSet<Data>)

Sets a whole list of new possible values for this variable, overwriting any existing ones.

§Arguments
  • name: The name of the variable to set the possible datasets for.
  • id: The Data/IntermediateResult identifier to add as possible return dataset for this variable.
source

pub fn get_func(&self, name: impl AsRef<str>) -> &HashSet<Data>

Returns the list of possible values for the given function. If it does not exist, returns an empty one.

§Arguments
  • name: The name of the function to get the possible datasets of.
§Returns

A reference to the list of possible values for the given function.

source

pub fn get_var(&self, name: impl AsRef<str>) -> &HashSet<Data>

Returns the list of possible values for the given variable. If it does not exist, returns an empty one.

§Arguments
  • name: The name of the variable to get the possible datasets of.
§Returns

A reference to the list of possible values for the given variable.

source

pub fn extend(&mut self, other: Self)

The extend function extends this table with the given one, i.e., all of the possibilities are merged.

§Arguments
  • other: The other table to merge with this one.
