Neo type representation for compiled contracts

Variants

Integer

Fields

signed: bool

bits: u16

Boolean

String

Address

ByteArray

Fields

fixed_len: Option<u16>

Array(Box<NeoType>, Option<usize>)

A Solidity array. The second field carries the FIXED length for T[N] (preserved so the ABI signature / selector is T[N], not T[]); None is a dynamic T[].

Implementations

impl NeoType

pub fn uint256() -> Self

Create a uint256 type

pub fn int256() -> Self

Create an int256 type

pub fn bytes_fixed(len: u16) -> Self

Create a fixed-size byte array

pub fn bytes_dynamic() -> Self

Create a dynamic byte array

pub fn is_value_type(&self) -> bool

Check if this is a value type (stored by value)

pub fn is_reference_type(&self) -> bool

Check if this is a reference type (stored by reference)

pub fn storage_size(&self) -> Option<usize>

Get the storage size in bytes (for value types)

pub fn type_name(&self) -> String

Get the type name as a string

pub fn canonical_abi_type(&self) -> String

EVM-ABI canonical type spelling used for function-selector and event topic0 hashing (keccak256(name(t1,t2,...))). Differs from Self::type_name in that STRUCTS expand to (field0,field1,...) tuples and the integer width is always explicit (uint256, not uint). Enums are already resolved to uint8 (Integer { bits: 8 }) during type resolution, so they canonicalize correctly here. Using the declared struct/enum NAME instead (the old behavior) produced selectors and event topics that disagree with Ethereum tooling for struct/enum parameters.

impl NeoType

pub fn from_solidity( ty: &str, structs: &[StructTypeMetadata], enums: &[EnumTypeMetadata], contract_types: &[String], ) -> Result<Self, TypeParseError>

pub fn from_solidity_with_aliases( ty: &str, structs: &[StructTypeMetadata], enums: &[EnumTypeMetadata], contract_types: &[String], type_aliases: &HashMap<String, String>, ) -> Result<Self, TypeParseError>

Resolve user-defined value type aliases before parsing.

If ty matches a key in type_aliases, the underlying type is used instead. This makes type Price is uint256 transparent to the type system. Aliases are also threaded into the recursive from_solidity_bounded walk so they get resolved when the alias appears as a struct field, array element, or mapping value (not just at the top level).

Trait Implementations

impl Clone for NeoType

fn clone(&self) -> NeoType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NeoType

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

Formats the value using the given formatter.

impl Eq for NeoType

impl PartialEq for NeoType

fn eq(&self, other: &NeoType) -> 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.
