Struct EvmWord 

pub struct EvmWord(pub [u8; 32]);

One 256-bit word, big-endian.

Printed the way traces spell stack words: 0x and the value in lowercase hex without leading zeros, and 0x0 for zero. A word read in any other spelling, padded or in upper case, is printed in that one.

Tuple Fields

0: [u8; 32]

Implementations

impl EvmWord

pub const ZERO: Self

pub fn from_u64(value: u64) -> Self

The word holding value.

pub fn from_be_slice(bytes: &[u8]) -> Option<Self>

The word holding the big-endian bytes, which must be at most 32 of them.

pub fn parse(text: &str) -> Result<Self, WordError>

Reads hex digits, with or without a 0x prefix and in either case.

Errors

Returns a WordError when there are no digits, a character is not a hex digit, or the value does not fit in 256 bits.

pub fn as_bytes(&self) -> &[u8; 32]

pub fn is_zero(&self) -> bool

pub fn to_u64(&self) -> Option<u64>

The value, when it fits in a u64.

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

The value, when it fits in a usize.
