Struct Scope 

pub struct Scope {
    pub id: u32,
    pub kind: u8,
    pub file_id: u16,
    pub parent_id: u32,
    pub start_line: u32,
    pub end_line: u32,
    pub name_offset: u32,
    /* private fields */
}

A scope node in the scope tree

Layout (24 bytes):

• id: u32 (4)
• kind: u8 (1)
• _padding1: u8 (1)
• file_id: u16 (2)
• parent_id: u32 (4)
• start_line: u32 (4)
• end_line: u32 (4)
• name_offset: u32 (4)

Fields

id: u32

Unique scope ID

kind: u8

Scope kind

file_id: u16

File ID where this scope exists

parent_id: u32

Parent scope ID (u32::MAX for root/file scope)

start_line: u32

Starting line number (1-indexed)

end_line: u32

Ending line number (1-indexed)

name_offset: u32

Offset into string table for scope name (if any)

Implementations

impl Scope

pub const fn new( id: u32, kind: ScopeKind, file_id: u16, parent_id: u32, start_line: u32, end_line: u32, name_offset: u32, ) -> Self

Create a new scope

pub const fn file_scope(id: u32, file_id: u16, end_line: u32) -> Self

Create a file-level (root) scope

pub fn scope_kind(&self) -> ScopeKind

Get the scope kind

pub fn is_root(&self) -> bool

Check if this is a root/file scope

pub fn is_function(&self) -> bool

Check if this is a function scope

Trait Implementations

impl Clone for Scope

fn clone(&self) -> Scope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Scope

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Scope

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Scope

fn eq(&self, other: &Scope) -> 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 Scope

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Scope

impl Eq for Scope

impl StructuralPartialEq for Scope
