Struct RustBuilder 

pub struct RustBuilder<'config> { /* private fields */ }

Rust 语言的 AST 构建器

RustBuilder 负责解析 Rust 源代码并构建抽象语法树 (AST)。 它使用 Pratt 解析器处理表达式中的运算符优先级，并支持所有 Rust 语法特性。

示例

基本用法:

use oak_core::Parser;
use oak_rust::{RustBuilder, RustLanguage, SourceText};

let language = RustLanguage::default();
let builder = RustBuilder::new(&language);
let source = SourceText::new("fn main() { let x = 42; }");
let result = builder.build(source, 0);

// 结果包含解析后的 AST
assert!(result.result.is_ok());

解析更复杂的 Rust 结构:

use oak_core::Parser;
use oak_rust::{RustBuilder, RustLanguage, SourceText};

let language = RustLanguage::default();
let builder = RustBuilder::new(&language);

let source = SourceText::new(
    r#"
struct Point {
    x: f64,
    y: f64,
}

impl Point {
    fn new(x: f64, y: f64) -> Self {
        Point { x, y }
    }
}
"#,
);
let result = builder.build(source, 0);

// 验证解析成功
assert!(result.result.is_ok());

Implementations

impl<'config> RustBuilder<'config>

pub fn new(config: &'config RustLanguage) -> Self

创建新的 Rust 构建器

Trait Implementations

impl<'config> Builder<RustLanguage> for RustBuilder<'config>

fn build<'a, S: Source + ?Sized>( &self, source: &S, edits: &[TextEdit], _cache: &'a mut impl BuilderCache<RustLanguage>, ) -> BuildOutput<RustLanguage>

Builds the structure from the source text.

impl<'config> Clone for RustBuilder<'config>

fn clone(&self) -> RustBuilder<'config>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
