# `RustQ.Rust.AST.Builder`
[🔗](https://github.com/dannote/rustq/blob/v0.11.1/lib/rustq/rust/ast/builder.ex#L1)

Expression, statement, and simple item constructors for `RustQ.Rust.AST`.

Alias the focused builders together:

    alias RustQ.Rust.AST.Builder, as: A
    alias RustQ.Rust.AST.ItemBuilder, as: I
    alias RustQ.Rust.AST.PatternBuilder, as: P
    alias RustQ.Rust.AST.TypeBuilder, as: T

The main families are:

  * items — `use/1`, `module/3`, `const/4`, `static/4`, `type_alias/3`,
    `impl/2`, and macro-item constructors
  * statements — `let/3`, `assign/2`, `if_let/4`, `return_stmt/1`, and
    block-oriented macros such as `block/1`, `match/2`, and `arm/3`
  * expressions — `call/2`, `path_call/3`, `method/4`, `struct_expr/2`,
    constructors such as `ok/1`, and binary-operation helpers
  * conversion — `expr/1`, `pat_expr/1`, `type/1`, and path normalization

`struct_expr/2` builds a struct literal. Use `I.struct/3` for a struct
declaration and `I.function/3` for a function declaration.
