Trait JsonAbiExt

pub trait JsonAbiExt: Sealed {
    // Required methods
    fn abi_encode_input(&self, values: &[DynSolValue]) -> Result<Vec<u8>>;
    fn abi_encode_input_raw(&self, values: &[DynSolValue]) -> Result<Vec<u8>>;
    fn abi_decode_input(
        &self,
        data: &[u8],
        validate: bool,
    ) -> Result<Vec<DynSolValue>>;
}

Provides ABI encoding and decoding functionality.

This trait is sealed and cannot be implemented for types outside of this crate. It is implemented only for the following types:

• Constructor
• Error
• Function

Required Methods

fn abi_encode_input(&self, values: &[DynSolValue]) -> Result<Vec<u8>>

ABI-encodes the given values, prefixed by this item’s selector, if any.

The selector is:

• None for Constructor,
• Some(self.selector()) for Error and Function.

This behaviour is to ensure consistency with ethabi.

To encode the data without the selector, use abi_encode_input_raw.

Errors

This function will return an error if the given values do not match the expected input types.

fn abi_encode_input_raw(&self, values: &[DynSolValue]) -> Result<Vec<u8>>

ABI-encodes the given values, without prefixing the data with the item’s selector.

For Constructor, this is the same as abi_encode_input.

Errors

This function will return an error if the given values do not match the expected input types.

fn abi_decode_input( &self, data: &[u8], validate: bool, ) -> Result<Vec<DynSolValue>>

ABI-decodes the given data according to this item’s input types.

Errors

This function will return an error if the decoded data does not match the expected input types.
