Struct Imports 

struct Imports {
    imports: Vec<String>,
    renaming: BTreeMap<(String, String), String>,
}

Datastructure to deduplicate, validate and generate imports

Fields

imports: Vec<String>

Import lines ready to use

renaming: BTreeMap<(String, String), String>

Renaming map: from module name and member name return the name to use in type hints

Implementations

impl Imports

fn create(module: &Module, module_parents: &[&str]) -> Self

This generates a map from the builtin or module name to the actual alias used in the file

For Python builtins and elements declared by the module the alias is always the actual name.

For other elements, we can alias them using the from X import Y as Z syntax. So, we first list all builtins and local elements, then iterate on imports and create the aliases when needed.

fn serialize_expr(&self, expr: &Expr, buffer: &mut String)

fn serialize_elts(&self, elts: &[Expr], buffer: &mut String)

Trait Implementations

impl Default for Imports

fn default() -> Imports

Returns the “default value” for a type.
