Enum VarScope 

pub enum VarScope {
    Param,
    Local,
    Field,
}

Variable scope type for InSymbol

Used to distinguish different kinds of “inner” symbols within a containing symbol (function, struct, etc.).

Path Format

• Parameter: my_crate::my_fn::$param::x
• Local variable: my_crate::my_fn::$var::result
• Struct field: my_crate::MyStruct::$field::name

Variants

Param

Function parameter: $param

Local

Local variable: $var

Field

Struct/enum field: $field

Implementations

impl VarScope

pub fn segment(&self) -> &'static str

Get the scope segment string

Examples

assert_eq!(VarScope::Param.segment(), "$param");
assert_eq!(VarScope::Local.segment(), "$var");
assert_eq!(VarScope::Field.segment(), "$field");

pub fn from_segment(s: &str) -> Option<VarScope>

Parse from a segment string

Examples

assert_eq!(VarScope::from_segment("$param"), Some(VarScope::Param));
assert_eq!(VarScope::from_segment("$var"), Some(VarScope::Local));
assert_eq!(VarScope::from_segment("$field"), Some(VarScope::Field));
assert_eq!(VarScope::from_segment("foo"), None);

pub fn is_scope_marker(s: &str) -> bool

Check if a string is a valid scope marker

Trait Implementations

impl Clone for VarScope

fn clone(&self) -> VarScope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VarScope

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VarScope

fn deserialize<__D>( __deserializer: __D, ) -> Result<VarScope, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for VarScope

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

Formats the value using the given formatter.

impl Hash for VarScope

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for VarScope

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for VarScope

impl Eq for VarScope
