A variable declaration.

Fields

id: usize

src: SourceLocation

name: String

name_location: Option<SourceLocation>

base_functions: Vec<usize>

constant: bool

Marks whether or not the variable is a constant before Solidity 0.7.x.

After 0.7.x you must use mutability. For cross-version compatibility use VariableDeclaration::mutability().

state_variable: bool

Marks whether or not the variable is a state variable before Solidity 0.7.x.

After 0.7.x you must use mutability. For cross-version compatibility use VariableDeclaration::mutability().

documentation: Option<Documentation>

function_selector: Option<String>

indexed: bool

mutability: Option<Mutability>

Marks the variable’s mutability from Solidity 0.7.x onwards. For cross-version compatibility use VariableDeclaration::mutability().

overrides: Option<OverrideSpecifier>

scope: Option<usize>

storage_location: StorageLocation

type_descriptions: TypeDescriptions

type_name: Option<TypeName>

value: Option<Expression>

visibility: Visibility

Implementations

impl VariableDeclaration

pub fn mutability(&self) -> &Mutability

Returns the mutability of the variable that was declared.

This is a helper to check variable mutability across Solidity versions.

Trait Implementations

impl Clone for VariableDeclaration

fn clone(&self) -> VariableDeclaration

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VariableDeclaration

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VariableDeclaration

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for VariableDeclaration

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

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 Walk for VariableDeclaration

fn walk(&self, visitor: &mut dyn Visitor)

impl Eq for VariableDeclaration

impl StructuralPartialEq for VariableDeclaration
