Functions

bytes32_to_hex_string

Convert a [u8; 32] to a bytes string.

deploy_bootstrap

Builds the deployment bootstrap that copies the runtime code into memory and returns it

format_even_bytes

Pad odd-length byte string with a leading 0

format_literal

Converts a literal into its bytecode string representation

format_push0 🔒

Formats a PUSH0 opcode if supported by the EVM version, otherwise falls back to PUSH1 0x00

hex_to_usize

Wrapper to convert a hex string to a usize.

literal_gen

Converts a value literal to its smallest equivalent PUSHX bytecode. Leading zeros are removed.

pad_n_bytes

Pad a hex string with n 0 bytes to the left. Will not pad a hex string that has a length greater than or equal to num_bytes * 2

push_min_width 🔒

Hex-encodes value as the smallest PUSHn (n >= 1) that holds it

str_to_bytes32

Convert a string slice to a [u8; 32] Pads zeros to the left of significant bytes in the [u8; 32] slice. i.e. 0xa57b becomes [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 165, 123]

str_to_vec

Convert string slice to Vec<u8>, size not capped
