Struct SourcePosition 

pub struct SourcePosition {
    pub line: u32,
    pub column: u32,
    pub offset: usize,
    pub length: usize,
}

源代码位置信息，表示代码在源文件中的位置

该结构体用于跟踪源代码的位置信息，包括行号、列号等。

Fields

line: u32

行号，从 1 开始计数

表示当前位置所在的行号，第一行为 1。

column: u32

列号，从 1 开始计数

表示当前位置所在的列号，第一列为 1。

offset: usize

字节偏移量，从 0 开始计数

表示从文件开始到当前位置的字节偏移量。

length: usize

长度，表示该位置所覆盖的字节数

通常用于表示标记或符号的长度。

Trait Implementations

impl Clone for SourcePosition

fn clone(&self) -> SourcePosition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SourcePosition

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SourcePosition

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SourcePosition

fn eq(&self, other: &SourcePosition) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for SourcePosition

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
