Struct alloy_dyn_abi::eip712::Resolver

pub struct Resolver { /* private fields */ }

Available on crate feature eip712 only.

A dependency graph built from the Eip712Types object. This is used to safely resolve JSON into a crate::DynSolType by detecting cycles in the type graph and traversing the dep graph.

Implementations

impl Resolver

pub fn from_struct<S: SolStruct>() -> Self

Instantiate a new resolver from a SolStruct type.

pub fn ingest_string(&mut self, s: impl AsRef<str>) -> Result<()>

Ingest types from an EIP-712 encodeType.

pub fn ingest_sol_struct<S: SolStruct>(&mut self)

Ingest a sol struct typedef.

pub fn ingest(&mut self, type_def: TypeDef)

Ingest a type.

pub fn ingest_types(&mut self, types: &Eip712Types)

Ingest a Types object into the resolver, discarding any invalid types.

pub fn linearize(&self, type_name: &str) -> Result<Vec<&TypeDef>>

This function linearizes a type into a list of typedefs of its dependencies.

pub fn resolve(&self, type_name: &str) -> Result<DynSolType>

Resolve a typename into a crate::DynSolType or return an error if the type is missing, or contains a circular dependency.

pub fn encode_type(&self, name: &str) -> Result<String>

Encode the type into an EIP-712 encodeType string

https://eips.ethereum.org/EIPS/eip-712#definition-of-encodetype

pub fn type_hash(&self, name: &str) -> Result<B256>

Compute the keccak256 hash of the EIP-712 encodeType string.

pub fn encode_data(&self, value: &DynSolValue) -> Result<Option<Vec<u8>>>

Encode the data according to EIP-712 encodeData rules.

pub fn eip712_data_word(&self, value: &DynSolValue) -> Result<B256>

Encode the data as a struct property according to EIP-712 encodeData rules. Atomic types are encoded as-is, while non-atomic types are encoded as their encodeData hash.

pub fn contains_type_name(&self, name: &str) -> bool

Check if the resolver graph contains a type by its name.

Warning

This checks by NAME only. It does NOT check for type
