Expand description

Nyar 常量池构建器

用于在汇编过程中收集和去重常量,最终导出为 NyarModule 所需的 Vec

Fields§

§constants: HashMap<NyarConstant, u16>

常量到索引的映射

§pool: Vec<NyarConstant>

按索引排序的常量列表

Implementations§

Source§

impl NyarConstantPool

Source

pub fn new() -> Self

创建一个新的常量池构建器

Source

pub fn add(&mut self, constant: NyarConstant) -> u16

如果常量已存在,则返回现有索引;否则将其添加到池末尾。

Source

pub fn add_int(&mut self, value: i64) -> u16

添加整数常量

Source

pub fn add_float(&mut self, value: f64) -> u16

添加浮点数常量

Source

pub fn add_string(&mut self, value: String) -> u16

添加字符串常量

Source

pub fn add_qualified_name(&mut self, value: QualifiedName) -> u16

添加限定名称常量

Source

pub fn into_vec(self) -> Vec<NyarConstant>

获取池中的所有常量

Source

pub fn len(&self) -> usize

获取常量池的大小

Source

pub fn is_empty(&self) -> bool

检查常量池是否为空
