Struct fuels_core::codec::ABIDecoder

pub struct ABIDecoder {
    pub config: DecoderConfig,
}

Fields

config: DecoderConfig

Implementations

impl ABIDecoder

pub fn new(config: DecoderConfig) -> Self

pub fn decode(&self, param_type: &ParamType, bytes: &[u8]) -> Result<Token>

Decodes bytes following the schema described in param_type into its respective Token.

Arguments

• param_type: The ParamType of the type we expect is encoded inside bytes.
• bytes: The bytes to be used in the decoding process.

Examples

use fuels_core::codec::ABIDecoder;
use fuels_core::traits::Tokenizable;
use fuels_core::types::param_types::ParamType;

let decoder = ABIDecoder::default();

let token = decoder.decode(&ParamType::U64,  &[0, 0, 0, 0, 0, 0, 0, 7]).unwrap();

assert_eq!(u64::from_token(token).unwrap(), 7u64);

pub fn decode_multiple( &self, param_types: &[ParamType], bytes: &[u8], ) -> Result<Vec<Token>>

Same as decode but decodes multiple ParamTypes in one go.

Examples

use fuels_core::codec::ABIDecoder;
use fuels_core::types::param_types::ParamType;
use fuels_core::types::Token;

let decoder = ABIDecoder::default();
let data: &[u8] = &[7, 8];

let tokens = decoder.decode_multiple(&[ParamType::U8, ParamType::U8], &data).unwrap();

assert_eq!(tokens, vec![Token::U8(7), Token::U8(8)]);

pub fn decode_as_debug_str( &self, param_type: &ParamType, bytes: &[u8], ) -> Result<String>

Decodes bytes following the schema described in param_type into its respective debug string.

Arguments

• param_type: The ParamType of the type we expect is encoded inside bytes.
• bytes: The bytes to be used in the decoding process.

Examples

use fuels_core::codec::ABIDecoder;
use fuels_core::types::param_types::ParamType;

let decoder = ABIDecoder::default();

let debug_string = decoder.decode_as_debug_str(&ParamType::U64,  &[0, 0, 0, 0, 0, 0, 0, 7]).unwrap();
let expected_value = 7u64;

assert_eq!(debug_string, format!("{expected_value}"));
