Struct brane_ast::ast::SymTable

pub struct SymTable {
    pub funcs: Vec<FunctionDef>,
    pub tasks: Vec<TaskDef>,
    pub classes: Vec<ClassDef>,
    pub vars: Vec<VarDef>,
    pub results: HashMap<String, String>,
}

Defines the SymTable, which is like a symbol table (very much so, even) but now specific to Workflowland.

Fields

funcs: Vec<FunctionDef>

Lists all edge functions used in the Workflow.

tasks: Vec<TaskDef>

Lists all tasks used in the workflow.

classes: Vec<ClassDef>

Lists all classes used in the Workflow.

vars: Vec<VarDef>

Lists only toplevel / global variables used in the Workflow. Any in-function variables will be kept in the function itself.

results: HashMap<String, String>

Lists intermediate results defined in this workflow and maps them to where to find them (the name of the location).

Implementations

impl SymTable

pub fn new() -> Self

Constructor for the SymTable that initializes it to empty.

Returns

A new SymTable instance.

pub fn with( funcs: Vec<FunctionDef>, tasks: Vec<TaskDef>, classes: Vec<ClassDef>, vars: Vec<VarDef>, results: HashMap<String, String>, ) -> Self

Constructor for the SymTable that takes the given vectors instead.

Arguments

• funcs: A vector of FunctionDefinitions that defines all functions in the table.
• tasks: A vector of TaskDefinitions that defines all external functions in the table.
• classes: A vector of ClassDefinitions that defines all classes in the table.
• vars: A vector of VarDefinitions that defines all variable in the table.
• results: A map with the intermediate results (as String, PathBuf pairs).

Returns

A new SymTable instance with the given definitions already added.

pub fn func(&self, id: FunctionId) -> &FunctionDef

Returns the function with the given index, if any.

Arguments

• id: The ID/index of the function to get the compile state of.

Returns

A reference to the corresponding FunctionDef.

Panics

This function may panic if id is out-of-bounds.

pub fn task(&self, id: usize) -> &TaskDef

Returns the task with the given index, if any.

Arguments

• id: The ID/index of the task to get the compile state of.

Returns

A reference to the corresponding TaskDef.

Panics

This function may panic if id is out-of-bounds.

pub fn class(&self, id: usize) -> &ClassDef

Returns the class with the given index, if any.

Arguments

• id: The ID/index of the class to get the compile state of.

Returns

A reference to the corresponding ClassDef.

Panics

This function may panic if id is out-of-bounds.

pub fn var(&self, id: usize) -> &VarDef

Returns the variable with the given index, if any.

Arguments

• id: The ID/index of the variable to get the compile state of.

Returns

A reference to the corresponding VarDef.

Panics

This function may panic if id is out-of-bounds.
